Today's example of sloppy journalism comes from the exalted pages of the New York Times. Here's the key passage, from an article reporting recent poll results showing that the American people are not enthusiastic about intervention in Syria:

"Americans are exhibiting an isolationist streak, with majorities across party lines decidedly opposed to American intervention in North Korea or Syria, according to the latest New York Times/CBS News poll."

Got that? If you're one of those people with doubts about the wisdom of intervening in Syria, you're an "isolationist." At a minimum, you're "exhibiting an isolationist streak."   

A degree of prudent skepticism about the wisdom of entering the Syrian morasse is not isolationism, of course. Genuine isolationism would mean severing our security ties with the rest of the world and focusing solely on defending sovereign U.S. territory. Genuine isolationism means ending U.S. alliance commitments in Europe and Asia and telling our various Middle Eastern allies that they were going to have to defend themselves instead of relying on help from Uncle Sam. Genuine isolationism would eliminate the vast military forces that we buy and prepare for overseas intervention and focus instead on defending American soil. Real isolationists favor radical cuts to the defense budget (on the order of 50 percent or more) and would rely on nuclear deterrence and continental defense to preserve U.S. independence. And the most extreme isolationists would favor reducing foreign trade and immigration, getting out of the U.N. and other institutions, and trying to cut the United States off from the rest of the world.

The overwhelming majority of people who have doubts about the wisdom of deeper involvement in Syria -- including yours truly -- are not "isolationist." They are merely sensible people who recognize that we may not have vital interests there, that deeper involvement may not lead to a better outcome and could make things worse, and who believe that the last thing the United States needs to do is to get dragged into yet another nasty sectarian fight in the Arab/Islamic world. But many of these same skeptics still favor American engagement in key strategic areas, support maintaining a strong defense capability, and see some U.S. allies as assets rather than liabilities.  

Hawks like to portray opponents of military intervention as "isolationist" because they know it is a discredited political label. Yet there is a coherent case for a more detached and selective approach to U.S. grand strategy, and one reason that our foreign policy establishment works so hard to discredit is their suspicion that a lot of Americans might find it convincing if they weren't constantly being reminded about looming foreign dangers in faraway places. The arguments in favor of a more restrained grand strategy are far from silly, and the approach makes a lot more sense to than neoconservatives' fantasies of global primacy or liberal hawks' fondness for endless quasi-humanitarian efforts to reform whole regions. 

Bottom line: The Times did its readers a disservice by using the pejorative term "isolationism" in such a sloppy fashion. As Brad DeLong likes to say: "Why, oh why, can't we have a better press corps?"   

I had planned to write about something else today, but instead I want to acknowledge the recent passing of Glenn Snyder, an important international relations theorist. I didn't know him well -- indeed, I think we met on only one occasion -- but I read a lot of his work over the years and admired both his intellectual ambition and the clarity of his thinking.

Snyder's scholarly career spanned more than four decades and he made contributions in several areas. He was a co-author of Strategy, Politics and Defense Budgets (1962) an important account of U.S. national security policymaking in the 1950s, contributing a lengthy study of Eisenhower's "New Look" in nuclear strategy. His 1961 book Deterrence or Defense: Toward a Theory of National Security was an early refinement of classical deterrence theory and one of the first applications of game theory to international affairs. In the 1970s, he and co-author Paul Diesing published Conflict among Nations: Bargaining, Decisionmaking and System Structure in International Crises, an ambitious attempt to integrate structural realism, game theory, and theories of decision-making to understand crisis outcomes. I pored over this book in graduate school and learned an enormous amount from Snyder's careful analysis; I must have read chapter 6 of that book ("Crises and International Systems") dozens of times. His 1984 World Politics article "The Security Dilemma in Alliance Politics" was another classic, and especially his elaboration of the reciprocal risks of "abandonment" versus "entrapment" (concepts first proposed by Michael Mandelbaum). This last line of work culminated in his magisterial book Alliance Politics, which combined careful deductive analysis with a series of deeply research case studies. 

Snyder was primarily a theorist, although he was also clearly  comfortable doing careful qualitative/historical research. And, like John Herz, he strikes me as someone who deserved a higher reputation in the field than he had. I think this may be due to the nature of his later work: Instead of picking a single big idea and promoting it incessantly,  both Conflict among Nations and Alliance Politics contained a lot of different ideas and came at their subjects from several angles at once. This comprehensive approach had a great deal of scholarly integrity to it, but it also made his works harder to pigeonhole. They were also too long to put on most graduate course syllabi, which meant that over time fewer graduate students were exposed to his work.  

In this way, the practical sociology of the IR business may have cost Snyder some recognition. Nonetheless, he was the author of not one but several classic books and articles, works that still reward a careful reading today. How many IR scholars can say the same? 

Most American global activism -- particularly of the military sort -- is justified by the claim that the security of the American homeland and the safety of U.S. citizens ultimately depends on controlling, shaping, influencing, deterring, compelling, dominating, destroying or in some way interfering with people in lots of far-away places. Yet the simple fact that we can do all those things in almost any corner of the world tells you two things that belie this justification. 

Specifically: 1) the United States still has military capabilities that dwarf everyone else's, and 2) we are so secure here at home that we don't have to spend much time or effort worrying about defending our own soil. Even if another terrorist group got as lucky as al Qaeda did back on 9/11, it wouldn't threaten our independence, long-term prosperity, or way of life unless we responded to such an attack in especially foolish ways (see under: Operation Iraqi Freedom). 

Call this the (In)Security Paradox: The main reason Americans are able to gallivant all over the world and expend lots of ink and bytes and pixels debating whether to get involved in Syria, Mali, Sudan, the Democratic Republic of the Congo, the South China Sea, etc., etc., is because the United States is actually very secure. What happens in most of these places isn't going to affect the safety or prosperity of the vast majority of Americans at all; U.S. citizens are much more likely to be harmed in an automobile accident, in a big storm, or in a household accident, than as a result of something happening in some distant land. We say we need to do these things to be secure; in reality, we are so secure that we have the luxury of intervening in wars of choice that ultimately don't matter very much. Which is one reason why we do.

This paradox got me thinking: what would happen if the United States were really insecure? What if we faced a malevolent peer competitor that was larger, more populous, more advanced, more productive, and more powerful than we were? What if our immediate neighbors were both hostile and military capable? What if all of the world's major powers were united in an alliance against us? What would our foreign and defense policy look like then? Here are a few thoughts.

#1: If the United States were really insecure, it would spend a lot more on defense and raise taxes to pay for it. If the US were really threatened, most Americans would accept diminished living standards and higher taxes in order to afford a more robust defense. You know, like we did in World War II. But because we are in reality very secure today, we don't spend that much on defense and we think we can still run the world on the cheap.

#2: If the United States were really insecure, you wouldn't see irresponsible and grandstanding senators acting like buffoons at confirmation hearings. If they did, they'd be rightly condemned as unpatriotic know-nothings who were placing the country at risk by pandering to powerful interest groups. More broadly, a real external threat would focus the national mind and encourage a more responsible bipartisan debate on critical national security questions, instead of the monkey show we often observe these days.

#3: If the United States were really insecure, it would have to make its defense dollars stretch as far as they could. For starters, we'd have a more rational military basing structure, instead of wasting resources just to keep pork-hungry members of Congress happy. 

#4: If the United States were really insecure, it wouldn't wage wars of choice at the drop of a hat. Instead, it would conserve its strength, keep its powder dry, and focus primarily on the biggest or most dangerous challenges. Translation: There'd be a lot less for liberal interventionists to talk about.

#5: If the United States were really insecure, it would be lot more careful in how it chose its allies and would be wary of giving any of them unconditional support. If the United States were really threatened, we'd want capable allies who didn't free-ride on our benevolence or take actions that got us into trouble with other important nations. And we wouldn't be all that picky about whether they were democratic or not. The main question would be whether being allied with them made us safer overall. Remember: Washington was allied with Stalinist Russia during World War II and with plenty of unsavory regimes throughout the long Cold War. When you face real threats, you can't afford to be either too picky or too generous.

#6: If the United were really insecure, we would hold military commanders and foreign policy advisors accountable for their failings and follies. Instead of firing people for sexual misconduct and other peccadillos (however regrettable they might be), we would mostly hold them accountable for their foreign policy performance. And that means serial blunderers like today's neoconservatives would be marginalized after driving the country into a ditch, and they wouldn't be treated as respected pundits and they wouldn't be advising presidential hopefuls. Only a state that is very, very secure can afford to keep listening to people whose have been wrong with such disastrous consistency.

#7: If the United States were really insecure, more academics would be engaged by important policy issues and fewer would spend their time writing obscure articles and books intended for a small number of like-minded navel-gazers. In other words, academic departments would place more value on policy-relevance, because it would be seen as an important way to help the nation deal with serious external challenges. I'd also expect Americans to put more attention and effort into teaching and learning about languages and foreign cultures, so that they could maneuver in a dangerous world more effectively. Only a truly secure nation can get away with being as ignorant of the outside world as the United States is, while at the same time believing it is somehow qualified and prepared to "lead" the world.

#8:  If the United States were really insecure, we would be even more likely to play hardball with our enemies. As Alexander Downes has shown, democracies don't follow Marquis of Queensbury's rules when they find themselves in a serious war of national survival. Instead, they are as likely to deliberately kill large numbers of civilians as non-democracies are. Although the United States often does things to other countries that it would regard as barbaric were they done to us (including targeted assassinations and economic sanctions that harm civilians), U.S. armed forces do go to considerable lengths to minimize collateral damage. That would change quickly if we thought our survival or security were really at risk.

#9: If the United States were really insecure, our civil liberties were be under even greater pressure than they are today. When countries are really scared, individual freedoms and constitutional guarantees tend to go out the window. (See under: Patriot Act, McCarthyism, "warrantless surveillance," Alien & Sedition Acts, etc.) If the United States were not the world's most powerful country and actually faced a serious threat to its national independence, my guess is that there would be even more aggressive efforts to police discourse, wiretap suspected fifth columnists, and generally interfere with our traditional freedoms. Among other things this is why it is critically important to weigh threats and risks carefully. If national security elites get away with inflating threats, it becomes easier to place more shackles on us at home. 

#10:  If the United States were really insecure, we'd have a very different attitude toward international law, and on devising legal and/or normative constraints on warfare. Right now, American dominance encourages us to use whatever forces we have at our disposal (drones, cyber capabilities, surveillance, etc.) because we assume we will always be better at it than anyone else. But if we were really threatened, we might be more interested in eliminating categories of weaponry that we recognize could do great harm to us and might not confer any real military advantage. Who knows? We might even ratify the Law of the Sea Treaty!

The flap over Chuck Hagel's nomination to be the next secretary of defense -- brought to you, like so many other foolish things, by hardliners in the Israel lobby -- has been a distraction from the real questions that the next secretary of defense ought to be ready to address. I happen to think Hagel is a good choice for the position, but he shouldn't get a free ride when he testifies tomorrow. In that spirit, here are the Ten Questions I'd Ask Chuck Hagel on Thursday.

Senator Hagel:

1. On China: "Do you think China's rising power poses a serious threat to U.S. interests? If its power continues to rise, should the United States continue to strengthen its Asian alliances and move more military forces to Asia? What other steps should the United States take now to protect its geopolitical interests in Asia, and how can we avoid a new Cold War there?"

2. On Taiwan: "As China's naval, air, and missile capabilities increase, defending Taiwan will become increasingly difficult. If at some point defending Taiwan is no longer militarily feasible, what should the United States do?"

3. On cyberwar: "Are you worried that America's use of cyberwarfare capabilities -- such as the famous STUXNET attack on Iran -- is setting a dangerous precedent for others? Given our growing dependence on computer networks, shouldn't we be actively pursuing some sort of a global regime to limit this danger, instead of assuming we will always be better at it than others?

Bonus follow-up on drones: "Same question: are we setting an equally dangerous precedent here? And do you agree with critics who say that current drone strikes are often counterproductive because they create as many extremists as they take out?"

#4. On nuclear weapons: "If it were solely up to you, sir, how many nuclear weapons would you maintain in the U.S. stockpile, even if other states did not reduce their arsenals at all?"

#5: On U.S.-Japanese relations: "The U.S.-Japanese security treaty is decidedly one-sided. As MIT professor Barry Posen points out, the treaty commits us to defending Japan while Japan promises to help. Shouldn't this arrangement be reversed? Why should America be more committed to defending Japan than the Japanese are? As secretary of defense, what will you do to produce a more equitable sharing of burdens between the U.S. and its wealthiest allies?"

#6: On torture:  "Are you comfortable with how the Obama administration dealt with the previous use of torture by U.S. personnel? Do you think the officials who authorized torture and other war crimes should have been prosecuted?"

#7: On Iraq and Afghanistan: "In the past decade, the United States has failed to achieve its strategic objectives in two major conflicts: Iraq and Afghanistan. Apart from the obvious lesson that we should not start foolish wars, what other lessons should the U.S. military be learning from these twin failures?"

#8: On the global military footprint: "The United States has hundreds of bases and other military facilities in every continent of the world; no other country comes even close. In the absence of a serious peer competitor, does our security really depend on this enormous global footprint? Which facilities could we do without?"

Bonus follow-up: "Defense experts also agree that America's basing structure at home is inefficient. As Secretary, are there any bases you would close or consolidate?

#9: On rape in the U.S. armed forces: "President Obama has recently authorized the deployment of women in combat roles. Yet sexual harassment and rape have reached epidemic proportions within the U.S. military, with over 3000 incidents per year being reported. What do you intend to do about this?"

#10: On veterans' benefits: "The United States should pay its soldiers a fair wage and stand by its veterans. Yet a number of budget experts now believe that ever-escalating benefit packages threaten our ability to maintain an effective defense. Do you think our current approach to military compensation is about right, or does it need to be fundamentally rethought? If the latter, how?"

If anybody asks him a few questions like that, they might even forget about some of those other issues, and the Senators might learn something useful about his qualifications and judgment.

I was in Beijing earlier this week, attending a conference on Sino-American relations. The conference was jointly sponsored by Beijing University and Harvard, and featured a number of prominent Chinese and American academics (and a few former policymakers). Our Chinese hosts were exceptionally welcoming, and the absence of clean air didn't prevent the other participants from making lots of interesting presentations. (For another summary of the proceedings, check out Alan Alexandroff's account here).

The panel on which I spoke was focused on how the United States and China could cooperate to enhance international security. I made five basic points and thought I'd pass them along to you.

1. Positive and Negative Forms of Security Cooperation. In theory (I argued), there are two broad forms that Sino-American security cooperation could take. The first type consists of positive acts of collaboration, such as counterterrorism measures or anti-piracy operations (as in the Gulf of Aden). One can also imagine more ambitious sorts of cooperation, as when the two states jointly approve U.N. Security Council sanctions against Iran. One could even imagine situations where China and the United States might join forces to halt some deep civil conflict, although that is obviously less likely.

The second type of security cooperation is essentially negative: Each side seeks to enhance its mutual security by limiting or restraining its activities in some important realm. Traditional arms control is an obvious example of this sort of cooperation, as was the U.S.-Soviet "Incidents at Sea" agreement. Sino-American agreement on a naval "code of conduct" or a ban on cyberattacks would be of this type as well.

In short, it is not hard to think of various ways that Washington and Beijing could cooperate to reduce the risk of international conflict. But is significant cooperation likely, and what factors might make it more or less probable?

2. Prospects for Cooperation. Unfortunately, the probability that two states will engage in significant acts of security cooperation -- and especially of the positive sort noted above -- is largely determined by the level of amity or trust between them. If they have generally positive relations, cooperation is fairly easy. If there is a lot of mutual suspicion, however, positive acts of cooperation will be hard to sustain because both sides may fear that the other is gaining some sort of advantage. Paradoxically: Security cooperation is easiest when it is least important and hardest when it would be most valuable. Welcome to the wonderful world of international relations!

3. Rival Grand Strategies. The main barrier to extensive Sino-American cooperation to enhance global security is the tension between their respective grand strategies. China's central strategic aim is to continue to grow economically, gradually acquire greater economic and military power, and eventually reduce or eliminate the U.S. security role in Asia. Not by conquest or force necessarily, but by co-opting or cowing neighboring states into distancing themselves from the United States. The reason is easy to fathom: Just as U.S. leaders wanted to expel the European great powers from the Western Hemisphere (see under: Monroe Doctrine), China's leaders believe they will be more secure in the long run if the United States does not have a large military presence near their borders and does not have close security ties with their neighbors.

The United States, by contrast, wants to stay in Asia in order to keep China from establishing a dominant position there. Since the U.S. became a great power, a core principle of its grand strategy was to prevent any single power from dominating either Europe or Asia. That's why the United States opposed Germany in World War I, fought Germany and Japan in World War II, and worked to contain the Soviet Union in the Cold War. If no single power dominates Europe or Asia, the states there will worry mostly about each other, and none are able to focus solely on the United States or do much to interfere over in the Western Hemisphere. Accordingly, the U.S. will want to stay in Asia, to backstop its allies there and prevent Beijing from dominating the region.

4. Will the U.S. and China Act with Restraint? If the United States and China each pursue their respective grand strategies energetically, conflicts of interest will be numerous and intense, and we will see lots of trouble down the road. In this sort of world, there won't be much security cooperation between the two sides, and there will be a very intense security competition in Asia itself, with each side trying to cultivate allies of its own and trying simultaneously to undermine the opposing coalition. But if the two states pursue their strategies in a restrained, even lazy, fashion, they'll find it easier to reach common ground on some issues and might even engage in positive acts of collaboration on occasion.

Alas, I don't think the latter outcome is likely. Restraint is not something the United States does very well, and the recent "pivot" to Asia is probably a harbinger of more to come. Fiscal constraints will put some limits on what the United States can do, but you can bet that the Pentagon sees a coming conflict with China as a major force driver and will push hard for an assertive approach and the preservation of our current "forward presence." Similarly, China's own level of restraint has declined as its relative power has grown, and Deng Xiaoping's strategy of the "peaceful rise" has been gradually giving way to a more assertive nationalism. If China's economic growth rate does not slow significantly, I wouldn't expect a lot of restraint on either side. (FWIW, I think a slowdown is nearly inevitable, which will create big problems for the Chinese leadership but might dampen tensions somewhat.)

5. Stability for the Long Term. Unfortunately, managing Sino-American relations over the long term will be even harder. If Chinese leaders are consistently smart, judicious, farsighted, clear-eyed, and wise, and if their American counterparts consistently exhibit similar qualities, then the two governments may be able to manage their future relations without serious trouble. But the history of both countries suggests that there is very little chance that these idyllic circumstances will prevail every year for the next several decades. Sooner or later, we are bound to get a cadre of foolish, impetuous, or incompetent leaders in one capital or the other, or maybe even both at the same time. If "wise leadership" is the prerequisite for managing Sino-American rivalry over the long haul, in short, history suggests one ought to worry. A lot.

The bottom line is that Washington and Beijing have an obvious interest in taking steps now that might make their relationship easier to manage in the future. In particular, establishing rules of the road for naval activity (similar to the earlier Incidents at Sea agreement) might reduce the danger of an unintended clash on the high seas. Reaching an understanding on the use of unmanned drones or cyberattacks would help too. Military-to-military contacts and other forms of elite exchange would be a good idea as well, so that elites in both societies know the people with whom they are dealing personally and are less likely to misread or misinterpret what they may do while in official positions. None of these steps makes rivalry disappear, but together they could help keep it from boiling over.

And that just might be the greatest contribution that these two states could make to international peace and security over the next 25 years.

If you'd like to start 2013 by sinking your teeth into the debate on U.S. grand strategy, I recommend you start with two pieces in the latest issue of Foreign Affairs. Both are by good friends of mine, and together they nicely limn the contours of a useful debate on America's global role. It's also worth noting that there are realists on both sides of this particular exchange, which reminds us that agreement on fundamental principles doesn't necessarily yield agreement on policy conclusions.

The first piece is Barry Posen's "Pull Back: The Case for a Less Activist Foreign Policy," and the second is Stephen Brooks, John Ikenberry, and William Wohlforth's "Lean Forward: In Defense of American Engagement." (A longer version of the B, I & W argument can be found in the latest issue of International Security; Posen's argument is outlined at length in a forthcoming book.)

Dedicated readers of this blog know that I am largely in agreement with Posen's position, so I'm going to focus today on what I find lacking in B, I & W. Like all of their work, it's vigorously argued and the longer version is richly documented. But all those footnotes cannot save it from some serious weaknesses.

First, B, I, & W straw-man their target by lumping together a group of strategic thinkers whose differences are at least as significant as their points of agreement. The "proponents of retrenchment" that they criticize range from libertarian isolationists who want to bring virtually all US forces home to "offshore balancers" like Posen who support a robust but less extravagant defense budget and favor not isolationism but merely more limited forms of international engagement. Needless to say, there is a world of difference in these views (even if both are broadly in favor of doing less), and so many of B, I & W's broad-brush charges miss their mark.

Second, there is something deeply puzzling about B, I & W's devotion to what Ikenberry used to called "liberal hegemony," and what he and his co-authors now prefer to call "deep engagement." B, I & W argue that deep engagement has been America's grand strategy since World War II and they believe it was the optimal strategy for the bipolar Cold War, when the United States faced a global threat from a major great-power rival. Not only was the USSR a formidable military power, but it was also an ideological rival whose Marxist-Leninist principles once commanded millions of loyal followers around the world.

Here's the puzzle: the Soviet Union disappeared in 1992, and no rival of equal capacity has yet emerged. Yet somehow "deep engagement" is still the optimal strategy in these radically different geopolitical circumstances. It's possible that U.S. leaders in the late 1940s hit on the ideal grand strategy for any and all structural conditions, but it is surely odd that an event as significant as the Soviet collapse can have so few implications for how America deals with the other 190-plus countries around the globe.

Third, B, I, & W give "deep engagement" full credit for nearly all the good things that have occurred internationally since 1945 (great power peace, globalization, non-proliferation, expansion of trade, etc.), even though the direct connection between the strategy and these developments remains contested. More importantly, they absolve the strategy from most if not all of the negative developments that also took place during this period. They recognize the events like the Indochina War and the 2003 war in Iraq were costly blunders, but they regard them as deviations from "deep engagement" rather than as a likely consequence of a strategy that sees the entire world as of critical importance and the remaking of other societies along liberal lines as highly desirable if not strategically essential.

The problem, of course, is that U.S. leaders can only sell deep engagement by convincing Americans that the nation's security will be fatally compromised if they do not get busy managing the entire globe. Because the United States is in fact quite secure from direct attack and/or conquest, the only way to do that is by ceaseless threat-mongering, as has been done in the United States ever since the Truman Doctrine, the first Committee on the Present Danger and the alarmist rhetoric of NSC-68. Unfortunately, threat-mongering requires people in the national security establishment to exaggerate U.S. interests more-or-less constantly and to conjure up half-baked ideas like the domino theory to keep people nervous. And once a country has talked itself into a properly paranoid frame of mind, it inevitably stumbles into various quagmires, as the United States did in Vietnam, Iraq, and Afghanistan. Again, such debacles are not deviations from "deep engagement"; they are a nearly inevitable consequence of it.

Fourth, B, I, & W largely ignore the issue of opportunity cost. Advocates of restraint like Posen (and myself) are not saying that the United States cannot afford to intervene in lots of overseas venues, they are saying that the United States would be better off with a smaller set of commitments and a more equitable division of labor between itself and its principal allies. If the United States were not spending more than more of the world combined on "deep engagement," it could invest more in infrastructure here at home, lower taxes, balance budgets more easily, provide more generous health or welfare benefits, or do whatever combination of the above the public embraced.

Fifth, B, I, & W argue that deep engagement works because hardly anybody is actively trying to balance American power. In their view, most of the world likes this strategy, and is eager for Washington to continue along the same path. On the one hand, this isn't that surprising: why shouldn't NATO countries or Japan prefer a world where they can spend 1-2% of GDP on defense while Uncle Sucker shoulders the main burden? More importantly, advocates of restraint believe doing somewhat less would encourage present allies to bear a fairer share of the burden, and also discourage some of them from adventurist behavior encouraged by excessive confidence in U.S. protection (which Posen terms "reckless driving"). If the U.S. played hard-to-get on occasion, it would discover that some of its allies would do more both to secure their own interests and to remain eligible for future U.S. help. Instead of bending over backwards to convince the rest of the world that the United States is 100 percent reliable, U.S. leaders should be encouraging other states to bend over backwards to convince us that they are worth supporting.

Moreover, even if most of the world isn't balancing U.S. power, the parts that are remain troublesome. For instance, "deep engagement" in the Middle East has produced some pretty vigorous balancing behavior, in the form of Iraq and Iran's nuclear programs, Tehran's support for groups such as Hezbollah, and the virulent anti-Americanism of Al Qaeda. Indeed, the more deeply engaged we became in the region (especially with the onset of "dual containment" following the first Gulf War), the more local resistance we faced. Ditto our "deep engagement" in Iraq and Afghanistan. And given that those two wars may have cost upwards of $3 trillion, it seems clear that at least a few people have "balanced" against the United States with a certain amount of success.

Sixth, reading B, I, & W, one would hardly know that the nuclear revolution had even occurred. Nuclear weapons are not very useful as instruments of coercion, but they do make their possessors largely unconquerable and thus reduce overall security requirements considerably. Because the United States has a second-strike capability sufficient to devastate any country foolish enough to attack us, the core security of the United States is not in serious question. The presence of nuclear weapons in the hands of eight other countries also makes a conventional great power war like World War I or World War II exceedingly unlikely. Yet despite this fundamental shift in the global strategic environment, B, I & W believe the United States must remain "deeply engaged" in Europe, Asia, and elsewhere in order to prevent a replay of the first half of the 20^th century.

To repeat: most of the strategists who reject "deep engagement/liberal hegemony" do not call for isolationism, a retreat to Fortress America, or a slash-and-burn approach to defense spending. On the contrary: they favor continued U.S. engagement, albeit in a more restrained, highly selective, and strategically sustainable way. They believe the United States should seek to maintain favorable balances of power in key regions, but that it does not need to provide all the military muscle itself and certainly should not try to dictate or control the political evolution of these areas with military force. They believe this approach would preserve core U.S. interests at an acceptable cost, and would be far better suited to the current distribution of global power.

"Deep engagement" might have been a good strategy for the Cold War, though even that proposition is debatable. But as you may have noticed, the Cold War is now over. Isn't it about time that U.S. grand strategy caught up with that fact?

In The Origins of Alliances (1987), I wrote:

"...the domestic situation of the United States may be more important than anything else. External events impinge on U.S. power; internal conditions generate it. Losses abroad will add up slowly (if at all) and will be compensated by balancing behavior by allies and by the United States itself. Thus a final prescription is to avoid policies that jeopardize the health of the U.S. economy. It is far more important to maintain a robust and productive economic system than it is to correct some minor weaknesses in defense capability or to control the outcome of some insignificant clash in the developing world." (p. 284)

I wrote those lines before the Cold War ended; they are even more true today. I thought of them as I read Edward Luce's perceptive discussion of America's deteriorating infrastructure in yesterday's Financial Times. Money paragraph:

"...most Americans are unaware of how far behind the rest of the world their country has fallen. According to the World Economic Forum's competitiveness report, U.S. infrastructure ranks below 20th in most of the nine categories, and below 30 for quality of air transport and electricity supply. The U.S. gave birth to the internet -- the kind of decentralized network that the U.S. power grid desperately needs. Yet according to the OECD club of mostly rich nations, average U.S. internet speeds are barely a 10th of those in countries such as South Korea and Germany. In an age where the global IT superhighway is no longer a slogan, this is no joke."

Why aren't Americans more concerned about their eroding infrastructure? Luce argues we've just adapted to delays, discomfort, and inefficiencies, much as the fabled frog supposedly doesn't recognize it is being boiled to death if the temperature in the pot rises slowly. But I'd argue there are a number of other forces at work.

The first is militarized patriotism: It's easier to get Americans to cheer when a B-2 or the Blue Angels does a flyover above a football game than it is to get them to take pride in a truly modern flight tracking system that would streamline commercial air travel. Similarly, it is easier to scare taxpayers by inflating foreign threats than it is to get them to put money into roads, bridges and other safety features that would reduce U.S. highway fatalities. We all know that nearly 3000 people died on September 11, 2001, but we never notice the deaths that might have been avoided if we had better hospitals, highways, and a more productive economy that kept fewer people in poverty.

Combine the hyping of foreign dangers with America's liberal idealism, and you get a country that will pour a trillion or more dollars into Iraq and Afghanistan, send special forces and drones into countries of little or no strategic value, and spend more time worrying about who's going to run Syria than it does worrying about conditions here at home.

Second, and following from the first, infrastructure improvements don't enjoy the support of large and well-organized lobbies constantly beating the drum for keeping our infrastructure in good working order. Such groups aren't non-existent, but their political power pales in comparison with other groups who are constantly thrusting their hands into the public till.

And then there's the time lag: Building road, bridges, internet capacity, air traffic control, a robust power grid, and protections against climate change/rising sea levels will be expensive and take years to complete. Equally important, the benefits accrue far into the future, long after today's politicians are gone. It takes foresight and a powerful sense of civic duty to invest in things that will mostly benefit future generations, which is why today's politicians are more likely to pander to today's voters and to well-heeled interest groups, instead of helping the country as a whole prepare for the future.

Lastly, as Luce notes, the GOP is no longer interested in federally-funded and managed programs for building national infrastructure, and their long campaign to convince Americans that government is always the problem and never the solution has undermined public support for a major campaign to rebuild the sinews of the U.S. economy. Their skepticism doesn't apply to military spending, however, even though it is hardly a model of efficiency (see my first point above).

This is not an argument for gutting defense, by the way; but cutting defense is clearly implied. More to the point, it is an argument for not squandering lots of money elsewhere when there are obvious needs here at home. And let's not forget that building infrastructure is actually something we know how to do, unlike the various costly projects of "nation-building" we've taken on elsewhere.

So here's a basic strategic principle that we've largely forgotten over the past seventy years, but which would serve us well today: Let's first make sure our leaders have done all we can to improve the lives of Americans -- you know, the citizens who work and pay taxes to support the government -- before they take on various international projects whose primary purpose is to benefit someone else. The United States shouldn't retreat into isolationism, of course, and it would still do things abroad that contributed directly and significantly to making Americans safer and more prosperous. Such actions would include support for an open world economy, maintaining "command of the commons," and helping maintain balances of power in key regions (but not trying to do it all ourselves).

Most importantly, we would not take on the various philanthropic projects embraced by neoconservative hawks, liberal imperialists, and other apostles of American "greatness" until we had addressed all of the obvious problems we are facing here at home. Let's first make that "shining city" really gleam, and then worry about which thugs are running Syria, or which politicians are fleecing depositors in Kabul.
