Will we eventually look back on President Obama's drop-in visit to Kabul as his "Mission Accomplished" moment? He's got a tough re-election battle to fight, the endless war in Central Asia isn't popular, and he wants to remind everyone that he's The Man Who Got Bin Laden. So he pulled a George W. Bush and burned up a lot of jet fuel racing to Kabul for a mostly meaningless photo op and a not-very convincing speech. This sort of posturing may help him get re-elected -- though I doubt it will have much effect -- but it's not going to help his long-term legacy when the U.S. is finally gone and Central Asia is on its own.   

As I mentioned a couple of weeks ago,  I don't put much value in the new U.S.-Afghan "strategic partnership." It has some symbolic value, I guess, and it can provide a fig leaf for our eventual withdrawal. If everything breaks the right way after 2014, it might even provide a general framework that facilitates some additional counter-terrorist activities. But it's merely an executive agreement, not a treaty, it is woefully short on specifics, and other people will be in charge in Kabul and Washington by the time the agreement runs out. If circumstances change in ways that give us reasons to renege (or give Afghan leaders grounds to want a different arrangement), this much-ballyhooed "partnership" won't be worth the pixels it's published with.

All told, nobody came off very well in this little episode. Presumptive GOP nominee Mitt Romney sounds both petty and silly trying to minimize Obama's genuine accomplishments against al Qaeda (and especially the elimination of bin Laden himself).  But Obama's attempt to turn the Afghan debacle into some kind of strategic triumph isn't much better, as Juan Cole and Ahmed Rashid make clear in separate pieces. All of which is more evidence that our agonizingly long electoral cycle is a major impediment to a smarter foreign policy.

Obama should not forget that the elder President Bush won a far more smashing victory in the 1991 Gulf War than we are going to get in Afghanistan, and he went down to defeat in 1992. It's still the economy, stupid, and most voters won't care much about bin Laden's demise when they go to the polls in November, no matter how often the president reminds them about it between now and then. Needless to say, that is precisely what Romney is counting on.

Note: In response to my previous post on the hazards of the new Atrocities Prevention Board, Andrew Miller of the Council on Foreign Relations' Center for Preventive Action offers the following alternative view. I'm not persuaded, but it is a thoughtful and intelligent rejoinder that I wanted to share with you. Take it away, Andrew....

Andrew Miller writes:

Stephen Walt's skepticism of the recently-announced Atrocities Prevention Board (APB) is understandable. New bureaucracies often create more problems than they solve. But, the APB is a worthwhile (albeit, modest) attempt to improve the government's mass atrocity prevention and response efforts. A close look at the board shows that it has the potential to both avert atrocities and lessen the likelihood of humanitarian interventions -- outcomes that realists, of course, can welcome with open arms.

The APB will help ensure that atrocity situations don't get sidelined in the policymaking process. The Clinton administration failed to address the 1994 Rwandan genocide in part because White House officials were focused on the dual crises in Bosnia and Haiti. Thus, as hundreds of thousands died in Rwanda, the genocide wasn't even a side-show for policymakers; it was a "no show" in the words of then-national security advisor Tony Lake.

The APB, as a standing body with senior officials (assistant secretaries and above), would be well-positioned to avoid such bloodshed becoming a "no-show". In tandem with the board, the president has vowed to set up "alert channels" that allow lower-level officials to raise red flags about potential atrocities. The APB could serve as a conduit in processing these warnings and ultimately getting them to the Oval Office if warranted.

Does that mean the U.S. military is more likely to find itself in places of negligible U.S. interests such as Rwanda? Simply put: No.

As the board's title suggests, it will focus on prevention. Thus, its success will be measured on its ability to prevent tensions from deteriorating to the point where intervention is even considered. With a preventive approach, the United States can save more lives while expending less blood and treasure. Preventive tools such as economic sanctions or threats of prosecution used to deter would-be perpetrators and protect would-be victims are almost always cheaper and less risky than large-scale military operations.

Given the board's interagency make-up, it can leverage these preventive tools rather than relying on the military to resolve crises. The APB will have representatives from the departments of State, Defense, Treasure, Justice, Homeland Security, among others, with the White House's director for multilateral affairs Samantha Power chairing the group. This broad representation will help make the military less of a go-to institution for dealing with atrocities as has been the case since the end of the Cold War.

It is fair to ask, what happens if preventive action fails? Or, as Walt puts it, "how likely is it that [the APB] will recommend doing little or nothing the next time something bad happens?" While the APB will probably recommend taking serious mitigating steps, there is a wide range of measures short of a large-scale military operation. Even Power, whom the National Interest has dubbed "Interventionista", stresses measures beyond "sending in the Marines." In her book A Problem from Hell, she lays out a host of policies that the Clinton administration could have taken during Rwanda: frequently denouncing the slaughter, beefing up the United Nations peacekeeper force there, jamming belligerent radio broadcasts used to coordinate attacks, threatening to prosecute the perpetrators, etc.

These are the sorts of measures that the APB will rely upon. In fact, the Obama administration has already used them to help end last year's bloodshed in Ivory Coast. Atrocities broke out there when opposition forces tried to unseat incumbent president Laurent Gbagbo who had lost the country's November 2010 elections. The administration subsequently slapped sanctions on the main perpetrators, backed the United Nations peacekeeping mission in-country, and ultimately supported a French troop deployment. Tensions in Ivory Coast remain today, but the mass killings have stopped.

The APB would not have made intervention in Ivory Coast any more likely. Walt accurately states that there are "good strategic reasons why outside powers choose to stay out of wars or brutal internal conflicts." Even if the APB had advocated for U.S. troops, there is little reason to believe that Obama would have deployed them to a place of negligible U.S. interests. (Perhaps the only effect Ivorian instability had on Americans was a rise in chocolate prices.) In other words, the president's strategic calculus on Ivory Coast was set, and the APB would not have changed that -- a good thing from the realist point of view.

Finally, Walt raises the uncomfortable reality of the United States' spotty human rights record. He argues that past U.S. misdeeds make the APB just another example of American "smug self-congratulation." If one takes a victim's perspective, however, this smugness seems less relevant. Srebrenica's Muslims, for example, surely would have appreciated American help in July 1995 regardless of U.S. sanctions on Iraq at the time. In the same vein, would the United States want to end its fight against human trafficking (modern-day slavery in many respects) given its pre-1860s history? Most realists (presumably Walt included) would say, no.

As this blog has made clear, realists are not divorced from morality. Like anybody else, they don't want to see Rwandan rivers choked with bodies or emaciated Bosnians behind barbed wire. They also don't want to see the United States' national security imperiled by military overstretch. The APB is a modest step toward reaching both ends.

How many of you know what the phrase "rope-a-dope" means? For those who don't, the phrase describes the strategy that Muhammad Ali used to defeat the heavily favored George Foreman in their heavyweight championship fight in Zaire in 1974, the so-called "Rumble in the Jungle." Foreman had demolished former champ Joe Frazier in two rounds in a previous bout, and most observers expected him to make short work of the older and smaller Ali. But Ali had prepared a clever strategy, and he spent the early rounds of the fight covering up and leaning against the ropes. Foreman landed lots of ineffectual blows, punched himself out, and became exhausted. Ali came off the ropes and knocked Foreman out in the 8th round.

What, you ask, does any of this have to do with international politics? I'll tell you. The "rope-a-dope" is a nice metaphor for an effective strategy for great power competition, somewhat analogous to the strategy of "bait and bleed." During the Cold War, for example, it made good sense for the United States to let the Soviet Union waste blood and treasure trying to win meaningless victories in places like Angola, or Afghanistan. By the same logic, Soviet leaders were smart to let us fight for years in Vietnam. In both cases the outcome of these conflicts didn't really matter very much to the overall balance of power, so letting the opponent punch themselves out trying to win was a clever approach.

Today, one could argue that China (and maybe a few others) are employing the "rope-a-dope" against us. And like poor George Foreman, we are falling for it. We get the honor of pouring money and lives into fruitless state-building projects like the current Afghan war, while China concentrates on building a stronger economy, gradually reforming its political order, and cultivating good working relations with other countries. Remaining bogged down in Central Asia or distracted by Iran also diverts us from focusing more attention on China, and makes us less likely to do some over-due "nation-building" here at home.

If we were smarter, of course, we'd be looking to saddle potential rivals with a lot of expensive order-keeping activities, and let them bear the burden in difficult or intractable local conflicts. That would give foreign policy elites less to do, perhaps, but that might not be such a bad thing either. Case in point: Why not let China worry about Pakistan's future, and get itself embroiled trying to manage the various quarrels and blood feuds in Central Asia? They could hardly do a worse job than we have, and we'd probably end up with a better relationship with most of the region. It is astonishing how much more popular we might be if we played hard-to-get more often, so that others would be less resentful of our constant sermonizing and interfering. Heck, if we stood aloof more often, some states would quickly do a lot more to try to make sure we didn't forget about them.

One caveat: The key to the "rope-a-dope" strategy was Ali's ability to prevent Foreman from landing telling blows in places that did matter. To make it work in international politics, the United States would a clear sense of which areas were strategically vital and which didn't matter all that much. And we'd also have to be able to distinguish between areas where it is useful to retain a lot of influence, and places where our main interest is simply to prevent some hostile power from dominating.  

This task won't always easy, but it shouldn't be impossible either. It does require a significant mental adjustment, however, back to a focus on U.S. national interest instead of vague and idealist notions about spreading our "values" and creating an American-centered "world order." American leaders have to stop thinking that the whole world is their responsibility and stop deluding themselves into thinking that we can and should "pay any price and bear any burden." From a purely American perspective, letting allies bear more of the burden in key regions and encouraging adversaries to blunder into sinkholes and quagmires, makes a lot more sense.

I have no idea if Dartmouth president (and public health expert) Jim Yong Kim is a good choice to head the World Bank or not. I'm not an expert on economic development, and I've heard both good and bad things about him from a number of friends and colleagues since his nomination was announced. But I am pretty sure that the Obama administration blew an opportunity to score some diplomatic points when they decided to push him for the job.

Here's the key issue: Because voting shares in the World Bank are determined by each member nation's contributions, the United States has a de facto veto over who gets to be Bank president. It's the old Golden Rule of International Organization: Those with the gold make the rules. By long-standing custom, the president of the World Bank has always been an American, while a European gets to lead the International Monetary Fund.

Surprise, surprise: Other countries find this situation objectionable. And especially when the U.S. uses its prerogative to foist candidates with dubious qualifications on the institution, such as former Secretary of Defense Robert McNamara (who helped lead the U.S. to disaster in Vietnam) or former Deputy Defense Secretary Paul Wolfowitz (who did the same for us in Iraq).

Of course, realists expect powerful states to use international institutions to advance their own interests, which is why they want to make sure that the people in charge are reliable. If I were president, I would want the World Bank to be led by a highly competent individual who wasn't about to harm U.S. interests. But a smart realist would also recognize that imposing the U.S. choice on others every single time is bound to trigger resentment, and encourage rising powers like China, Brazil, India, and others to redouble efforts to break Washington's stranglehold. And every time the United States has to twist arms or use its privileged position to get its way, other states quietly seethe and anti-American forces are handed another nice talking point to use to undermine the U.S. image around the world.

Which is why I think the Obama administration missed a golden opportunity when it failed to embrace the nomination of Ngozi Okonjo-Iweala, the Nigerian Minister of Finance minister and former World Bank Managing Director. I can't speak with authority about her qualifications, although she does have a B.A. from Harvard (magna cum laude) and a Ph.D. in regional economic development from MIT. I'm also struck by the endorsement she received from renowned trade economist Jagdish Bhagwati in a letter to the Financial Times, where he said that his own personal experience had convinced him that "she can outwit and outsmart almost any policy economist I know."

To be clear, I'm not arguing that Okonjo-Iweala is axiomatically a better choice than Kim, although she certainly appears to be equally (and maybe better) qualified. My point is about the diplomatic repercussions of this decision and the broader approach that the United States ought to be taking in world affairs. Given how powerful the United States still is, a primary goal of U.S. foreign policy should be to make America's privileged position as palatable to others as possible. One way to do that is to make symbolic concessions on minor issues on occasion, in order to build good will and to convey a certain regard for others's sensitivities. You know: a "decent respect for the opinions of mankind." So when Washington gets lucky and the African Union endorses a Nigerian economist with a B.A. from Harvard and a Ph.D. from MIT, who also has ample experience at the World Bank, and who is a woman of color to boot, the smart thing to do is get behind it immediately. This course is such an obvious no-brainer that I'm amazed the Obama administration didn't leap at the opportunity.

And by the way, having a non-American as president of the World Bank wouldn't set an unfortunate precedent. The United States would still have the voting rules in its favor, and it could still veto future candidates that it deemed unacceptable. But in this case the United States missed an opportunity to build some good will at little or no cost, and it's going to come back to haunt us down the road. And woe unto us if Kim gets the job and turns out to be a dud.

There's been a lot of needless hoopla over Obama's "open mic" comment at the Nuclear Security Summit, including an almost certainly ghost-written piece by Mitt Romney here at FP. Obama was overheard telling Russian President Dmitri Medvedev that he "would have more flexibility" to negotiate a deal on missile defense after the election, which is both correct and hardly a state secret. The flap illustrates the main point I was trying to make a few days ago, when I wrote about how the absurdly long U.S. election cycle was a major impediment to a more effective foreign policy. (It may also be an impediment to Romney's chances, because the longer the campaign goes on, the more opportunities he has for foot-in-mouth moments that expose his ignorance about foreign policy, including his silly comment about Russia being our major geopolitical rival).

In any case, the incident got me thinking about how much the arms control agenda has changed since the heyday of the Cold War. Back then, there was a serious constituency in the United States pushing nuclear arms control, which saw it as key to reducing the risk of nuclear war, managing the U.S.-Soviet relationship, and dampening the danger of international conflict more generally. Arms control was intended to save some money, preserve each side's second-strike deterrent capabilities, and help stabilize the political relationship between Moscow and Washington. It was thus a key ingredient in the basic agenda of détente, which sought to keep U.S.-Soviet competition within bounds. (One can argue about how effective it was, but it is worth noting that nuclear war didn't occur, and the U.S. and its allies triumphed over the Soviet Union without fighting a war with them.)

Accordingly, the main items on the arms control agenda involved direct negotiations with our Soviet adversaries (the SALT and START treaties, the INF treaty on intermediate nuclear forces in Europe, etc.). These efforts involved tough and protracted negotiations between more-or-less equals (even though the U.S. and its allies were a lot stronger than the Soviet Union and its various clients), and there was no possibility of either side issuing ultimatums or imposing a one-sided deal on the other. The other main arms control item was the Non-Proliferation Treaty (NPT), and this arrangement resulted from tacit collusion between the two superpowers to preserve their own nuclear superiority. After all, the basic NPT deal allowed nuclear powers keep their own arsenals (in exchange for pledges to share nuclear technology and make some sort of long-term effort disarmament), while putting in place a regime that made it much harder for other states to join the nuclear club.

But what about now? Since the end of the Cold War, the "arms control" agenda has become decidedly one-sided. Yes, there's been a not-very-significant "New Start" treaty with Russia, which didn't alter the basic strategic relationship at all and which hardly anybody (including Governor Romney) has paid much attention to. The real action in arms control has been a series of U.S.-led efforts to get states to give up their existing arsenals or abandon existing nuclear programs. In the 1990s, we put tremendous pressure on Ukraine, Kazakhstan, and Belarus to give up the arsenals they inherited from the former Soviet Union, and we eventually succeeded. Then the United States nearly launched a preventive war against North Korea in 1994, and did various deals (e.g., the "Agreed Framework") to try to head off their development of nuclear weapons. We invaded Iraq in 2003 to stop Saddam's "Weapons of Mass Destruction" programs (which turned out to be fictitious -- our bad), and have been ratcheting up economic sanctions and waging a covert war against Iran to try to keep Tehran from getting too close to the nuclear weapons threshold. And we keep saying "all options are on the table," which is a threat to use force.

In short, instead of "arms control" being the product of mutual negotiation, as it was in the Cold War, it now consists of the United States making demands and ramping up pressure to get weak states to comply. Instead of being primarily a diplomatic process aimed at eliciting mutually beneficial cooperation (which might also help ameliorate mutual suspicions with current adversaries), arms control has become a coercive process designed to produce capitulation. This approach may have worked in a few cases (e.g., Libya, although even there the Bush administration made certain concessions to secure a final deal), but its overall track record is paltry. After all, North Korea eventually went ahead and tested a nuclear device, and escalating pressure on Iran has yet to convince its leaders to abandon their enrichment program. And as I've noted before, using military force would not eliminate Iran's ability to develop weapons if it wishes, and could easily convince them that they had not choice but to go ahead and weaponize.

Because material power is still the central currency in world politics, this tendency doesn't surprise me all that much. When the United States has to deal with near-equals, it understands that bargaining is necessary and that a successful outcome requires patience and compromise. But today, we think we can impose our will on almost anybody, so any sort of compromise is regarded as some sort of craven appeasement. But even a country as powerful as the United States cannot simply dictate to others -- as we should have learned by now from our experiences with Iraq, Afghanistan, and a few others -- and a disdain for genuine diplomacy (as opposed to merely issuing ultimatums and imposing sanctions) is getting in the way of potential deals that could reduce the risk of proliferation, dampen the danger of war, and enable U.S. leaders to turn their attention to other priorities. Being the world's #1 power confers many advantages, but it can also be a potent source of blind and counterproductive arrogance.

One important thing to remember about the Annual Festival of Hyperbole (aka the AIPAC Policy Conference) is that the views of the attendees aren't representative of most Americans, let alone American Jewry, and that a lot of the speakers who are there to pay homage don't mean most of what they are saying. At least I hope not. President Obama walked a wobbly tightrope as well as one could have expected; the depressing feature is that he had to perform these sort of acrobatics at all. That's politics, folks.

Next up: Obama and Netanyahu meet at the White House. My basic take is that Netanyahu's view and Obama's view are essentially mirror-images of each other. Netanyahu says Iran is an "existential" threat to Israel, while he sees the Palestinians as just a problem to be managed. So he wants Iran's nuclear program ended, and by force if necessary, while the peace process drags on interminably. By contrast, Obama sees Iran as a problem to be managed through patient diplomacy, but he thinks the Palestinian issue is the real existential threat to Israel's future (and a continued liability for U.S. strategic interests). He'd like to put that one to rest ASAP, except that he's been forced to back down every time he's tried and he knows he can't say much about it between now and November.

Those interested in further reflections on this matter can take a look at this op-ed in the Financial Times, co-authored with John Mearsheimer.

Xi Jinping has been to Washington, and is now traipsing across the country. Apart from traffic snarls in Washington and some feel-good stories from Iowa, I wonder how significant the visit was, or whether this sort of tete-a-tete matters as much as we think.

I wasn't present for any of the private discussions, of course, and I have no idea what impression top U.S. officials took away from their exchanges. I know even less about what Xi or his entourage concluded from the exchanges. But here's why I'm inclined to downplay the significance of the visit.

First, as a good realist, I think that the basic state of Sino-American relations will be driven more by balances of power and configurations of interest than by the personalities of individual leaders. As I've noted before, if China continues to grow more powerful, Bejing and Washington will view each other with an increasingly wary eye and are likely to find more issues about which to conflict. A serious security competition -- especially in East Asia -- will be likely (which does not mean that war is inevitable or even likely, by the way). Again assuming China's continued ascent, I'm guessing this will occur no matter who is in power in each country.

The second reason I'm inclined to downplay this week's meeting has to do with timing. Assuming Xi does make it to the top of the Chinese hierarchy, he will only be president for a maximum of ten years. A lot can happen during his tenure, but China's overall power position isn't going overtake America's in that period and I believe the odds of a serious Sino-American quarrel will still be rather low while he is in office. The real test of Sino-American relations will still lie some distance into the future. As a result, what Xi's individual qualities and likely preferences matter somewhat less. (To the extent that they do, I'd argue that what really matters is Xi's ability to manage China's economy and its internal politics, not his views on specific foreign policy issues).

Third, although China remains an authoritarian state, its president is not an absolutist ruler. Whatever Xi's personal tendencies might be, he will be operating within a political system that will inevitably constrain what he's able to do. Again, that's not to say that his own character is irrelevant, only that its impact on actual policy will be warped, limited or shaped by other political forces.

The last reason why I'm inclined to discount the significance of this sort of visit is the fact that nobody can read minds. One can never be sure that you really know what someone else is thinking, especially in the sort of highly-scripted, read-your-talking-points type of sessions that predominate. You may be able to get a pretty good read on other leaders if you spend a lot of time with them (think of Reagan, Shultz and Gorbachev, Kissinger and Sadat, the interlocutors at Camp David in 1978, etc.) but that's not necessarily certain if you're dealing with someone who is a world-class dissimulator. So any impressions formed on this visit can only be provisional, which perforce lowers the value of the various exchanges.
Of course, the relative impact of individual, domestic, and international-structural causes is a long-running issue in the IR field (see under: level of analysis problem, or this classic work). I'm hardly going to resolve it in a single blog post. And to repeat: I'm not suggesting that leaders' personalities and propensities don't matter at all, or that they might not be extremely significant in certain circumstances. But on the whole, the rapt attention paid to high-profile visits of this sort is exaggerated, and especially right now. In other words, the future course of Sino-American relations is going to be determined primarily by enduring structural forces (or conceivably domestic interests), and not by whether Xi Jinping is smart, patient, risk-averse, impetuous, witty, cranky, brilliant, crafty, obtuse, ignorant, well-briefed, or whatever.

None of this is to argue against having top leaders in China and the United States get to know each other a bit better. And nothing will stop journalists (and bloggers!) from writing a lot of stories when they do explaining What It All Means. But in my case, I think it means less than you've been told up till now.

If you are someone who is inclined to favor hawkish responses to foreign policy problems, then your choice for president should be Barack Obama. Not because Obama is especially hawkish himself, or interested in prolonging costly and failed commitments in Iraq or Afghanistan. For that matter, his administration is making a modest and fiscally necessary effort to slow the steady rise in Pentagon spending, and they seem to understand that war with Iran is a Very Bad Idea. (It is of course no accident that military action there is being promoted by the same folks who thought invading Iraq was a Very Good Idea. But I digress.)

So why should hawks vote for Obama? As Glenn Greenwald and Greg Sargent have argued most forcefully, it's because Obama can do hawkish things as a Democrat that a Republican could not (or at least not without facing lots of trouble on the home front). It's the flipside of the old "Nixon Goes to China" meme: Obama can do hawkish things without facing (much) criticism from the left, because he still retains their sympathy and because liberals and non-interventionists don't have a credible alternative (sorry, Ron Paul supporters). If someone like John McCain, Mitt Romney, Rick Santorum, Newt Gingrich or George W. Bush had spent the past few years escalating drone attacks, sending Special Forces into other countries to kill people without the local government's permission, prosecuting alleged leakers with great enthusiasm, and ratcheting up sanctions against Iran, without providing much information about exactly why and how we were doing all this, I suspect a lot of Democrats would have raised a stink about some of it. But not when it is the nice Mr. Obama that is doing these things.

The key to making this work, as Andrew Bacevich suggests here, is to insulate the vast majority of the American population from the effects of this effort. Obama understands that there's no stomach for big, costly, and inconclusive wars like Iraq and Afghanistan (he's right, and there's also little to be gained from them). But he and his advisors are betting that the American people will tolerate active efforts to hunt down and kill perceived bad guys, provided that the costs are low and occur far away and mostly out-of-sight. And it is in this context that one has to view recent proposals to give U.S. Special Forces greater presence, autonomy, and capability, an idea that remains controversial within military circles.

In other words, we are engaged in a grand strategic experiment: can the United States make itself more secure by dispatching troops and drones to various corners of the world, with the explicit mission of killing anyone we think might be a "terrorist?" At first glance, this approach certainly looks better than the debacle in Iraq, and it consistent with the "laser-like focus on Al Qaeda" that some of us recommended way back in 2001. But it is not without its own dangers, of which the following strike me as especially paramount.

The first danger lies in the secrecy with which these activities are now shrouded. We don't really know who is being targeted for attack, or what the error rates are. Is it really true that U.S. forces have targeted not just suspected terrorist but also the people who seek to provide medical or rescue assistance after an attack, on the assumption that the rescuers are in cahoots with original targets? How often do we make honest mistakes? How reliable is the information on which targeting is being conducted?

The second danger -- "blowback" -- follows from the first. What if we end up creating more new terrorists than we kill? What if aggressive efforts to hunt down Al Qaeda in Pakistan ends up destabilizing the nuclear-armed Pakistani state and convinces lots of people there that the United States is inherently hostile? Are we going to understand that such hostility didn't emerge solely because these people "hate our values," but rather because a cousin, brother, or fellow countrymen was targeted by an American drone, and maybe in error? The less we know about what U.S. forces are doing, the harder it will be for us to understand why some people don't like us that much.

A third danger is imitation. There is every reason to assume that other states, as well as some non-state actors, will decide to follow us down this particular path. The United States used to say that it opposed "targeted assassinations," but now we we are legimitizing this practice and others are bound to get into the act too. Similarly, by paying less and less attention to the old norm of sovereignty, we are making it more difficult to object when other states start interfering in each other's internal affairs. If we can send drones and/or special forces into any country we choose, why can't other states violate national borders in order to advance some policy objective of their own? What are we going to say then?

Fourth, is this a temporary expedient or a slippery slope? A case can be made that Obama's approach is a smart response to the dangers posed by Al Qaeda and its progeny, and that his policies reflect a temporary necessity. In this view, groups like Al Qaeda arose in a particular historical and political context, and they are gradually being attrited by an increasingly precise and effective strategy. If you believe this, then you might also believe that eventually the war on terror will be won, and that eventually we will be able to ratchet back these activities, shut down Guantanamo, rescind the Patriot Act, get rid of those demeaning scanners at airports, and cut back or quit those drone strikes. One could even argue that what we are really seeing is a last flurry of activity as we exit Iraq, prepare to exit Afghanistan, and start pivoting toward East Asia.

I'd like to believe that, but as Bacevich suggests, it is at least as likely that we have entered a new phase in American strategy from which it may be difficult to extricate ourselves. The problem is that we have these new capabilities (i.e., drones), and Obama and Bush have established the precedent of a "don't ask, don't tell" approach to warfare that keeps most of what we are doing in the dark. My fear is that future presidents are going to find those capabilities and that precedent very hard to resist. When hammers (drones?) are cheap, it's tempting to buy a lot of them and you'll tend to see a world full of nails. Drug lords in Mexico causing trouble? Let's just take 'em out. Tired of Hugo Chavez and his shenanigans? We've got an app for that. Sickened by the carnage in Syria? Let's give Assad and his underlings the same treatment we gave Ghaddafi. And so on. But most actions generate unintended consequences, and I suspect that trying to be the global policeman -- or in the minds of some, the global vigilante -- on the cheap may be a decision we'll eventually regret.

Dan Drezner misunderstands me, and not for the first time. Specifically, in my post on the debate over whether China is overtaking the United States, I neither said nor implied that "developing accurate assessments about the power balance between China and the United States" was not important. My point, rather, was that focusing so heavily on whether China was "catching up" ran the risk of distracting us from equally important issues, such as America's ability to advance its interests more broadly.

In particular, even if everyone agreed that China was not catching up at present, it might still be true that the United States was less able to get its way than it used to be. And even if Michael Beckley is correct that China is not "catching up," it does not necessarily follow that the United States is in great shape, or that it hasn't committed some costly blunders that it ought not to repeat.

Dan is correct to say that the United States is still the world's most powerful country, but of course I never said it wasn't. Indeed, America's enduring assets are a point that I emphasized in my own post and in the National Interest article to which I linked. But the real issue is whether our capacity to "run the world" is more constrained than it used to be. After World War II, the U.S. was able to create a working international trade and monetary order, create new alliance partnerships in Europe, Asia, and the Middle East, and pretty much run those partnerships on its own terms for decades. Back in those days, the U.S. could devote fully five percent of its GDP to a single initiative like the Marshall Plan without batting an eye. And then we spent the 1950s subsidizing our allies' recovery. Can anyone imagine our doing something similar today (i.e., spending five percent of GDP (that is, about $700 billion) on economic aid for anyone, in addition to our normal expenditures for defense and foreign affairs? And let's not forget that it has been two decades since the last successful multilateral trade round, which is another indicator of how power has diffused.

But one doesn't have to go all the way back to 1947. I'd argue that U.S. influence was significantly higher in 1999, in part because we enjoyed a budget surplus,but also because we had a reputation for military prowess and idealism that made many states want to be on our side. For lack of a better term, let's call it soft power.

Today, by contrast, we have budget deficits looming as far as the eye can see. We've lost one war (Iraq) and are going to lose another (Afghanistan). Our global image has been tarnished by events like Abu Ghraib, Guantanamo, the persistent use of drones, and our decidedly one-sided policies elsewhere in the Middle East. Israel ignores our efforts to foster peace, Saudi Arabia ignored us when it intervened in Bahrain, both Pakistan and Afghanistan routinely lie to us, and we have little influence over the political evolution underway in places like Egypt or Libya. Turkey may be cooperating on some issues, but it is hardly as compliant an ally as it was back in the days of the old military government. And so on.

Again, this situation doesn't mean the U.S. is devoid of all influence or a "pitiful, helpless giant." But at the same time, to conclude that all is well because China is not about to supplant us as the world's number 1 power strikes me as a dangerous misreading of recent trends.

Dan is undoubtedly correct to point out that many states still want to rely on U.S. power to help them deal with local security problems, and that the United States is sometimes able to elicit support from like-minded allies if we work really, really hard at it. It is therefore not surprising that a number of Asian countries are eager for U.S. help to counter the challenges posed by a more powerful China. But as I've argued previously, forming a balancing coalition against a rising China is not going to be a walk in the park, and it will require adroit diplomacy to overcome the inevitable dilemmas of collective action and other incentives to "free-ride" on Uncle Sam.

One can also raise at least two questions about Beckley's optimistic assessment. If China hasn't been "catching up," then why are so many states in Asia worried about it? It's possible that they have fallen for the hype too, but at a minimum it ought to give us some pause to realize how seriously China's neighbors see its growing capabilities. Second, as Tom Christensen and some others have previously noted, China does not have to equal the United States in order to pose a greater challenge for us (which is a point that could also be said, on a far lesser scale, for some other countries).

To see this, just ask yourself the following question: if the U.S. were contemplating a direct test of strength with China, would it be better for the United States for this to have occurred in 1992, 2012, or 2022? I'd argue the former, and I'll bet almost anyone in the U.S. military would agree. That's not to say the United States would not win a direct test of strength both now and well into the future, it's just to say that it would have been easier in the past than it is likely to be in the future. And if that inference is correct, then it tells you something about whether Beckley's optimism is fully warranted.

All of which leads to stand by my original post. Of course we should pay attention to the balance of power between the U.S. and China, and Beckley's original article is an important contribution to that effort. But it would be a mistake to read Beckley's reassuring conclusions as evidence that everything is just hunky-dory with current U.S. foreign and defense policy, and to conclude we hadn't spent a lot of the past decade wasting a lot of blood and treasure on fools' errands.
