I have only one thing to say about Gary Schaub Jr. and James Forsythe Jr.'s op-ed in today's New York Times, published under the title "An Arsenal We Can All Live With."
Amen.
Schaub and Forsythe argue that the United States could satisfy all its legitimate security requirements with an arsenal of 311 nuclear warheads, dispersed among bombers, submarine-launched ballistic missiles, and ICBM's. Not a thousand. Not 1,550 plus a few thousand more in reserve. Only 311. That's all.
Actually, I think that number might still be too large, because you only need a very small handful of nuclear weapons (e.g., maybe a dozen?) to inflict a level of damage that no political leader could tolerate. As former National Security Advisor McGeorge Bundy famously wrote:
A decision that would bring even one hydrogen bomb on one city of one's own country would be recognized in advance as a catastrophic blunder; ten bombs on ten cities would be a disaster beyond history; and a hundred bombs on a hundred cities are unthinkable."
American policymakers clearly understand the compelling logic of minimum deterrence, or else they wouldn't be so worried when states like North Korea or (maybe) Iran seek to join the nuclear club. U.S. leaders recognize that even a handful of nuclear weapons in the hands of a hostile country constrains what we can do to that country (which is of course why some states want to get them in the first place). But if a very small number of weapons can induce such sobriety on our part, why exactly do we need thousands, especially when our conventional forces are already far stronger than any other country on the planet?
Of course, the fact that deterrence isn't sensitive to the actual number of weapons also implies that having more weapons than we need isn't that dangerous, provided that you are very, very certain that you won't lose one, that your large arsenal won't encourage others with less reliable security arrangements to build up, and provided you have lots of money to pay for an arsenal you don't really need. But since I like saving money, would prefer that other states either didn't get nuclear weapons or kept their own arsenals small (and therefore easy to guard), and believe that decreasing the number of warheads in the world is an important step in improving overall nuclear security, I think Schaub and Forsythe's article should be taken seriously.
But I doubt it will. Schaub and Forsythe's analysis is based on careful strategic reasoning, and their conclusions challenge both the bureacratic interests of the professional military and the more atavistic instincts of the body politic. A serious attempt to implement their recommendations would elicit howls of protest from hawkish politicos and pundits, who will maintain that the world's only superpower also needs the biggest pile of (unusable) bombs in order to preserve its capacity to swagger, even if they can't actually explain how we would ever use that many weapons or how we derive any practical political benefits from this alleged "superiority." In the hothouse world of political commentary, insisting that "size doesn't matter" isn't a winning argument, even when logic and evidence are overwhelmingly on its side.
"...the bureacratic interests of the professional military..."
Actually, the analysis is very solicitous of the bureaucratic interests of the military. 311 is arrived at by figuring out how few warheads something close to our current structure could carry. It breaks down to 192 SLBMs on 12 subs with 2 in overhaul, 100 ICBMs and 19 B-2's with one warhead each. In other words, the same submarine fleet we have now, the same nuclear B-2 fleet we have now, and 100 of the 450 ICBMs we have now.
The Op-Ed shows minimal thinking about how many nukes we need to accomplish missions. For reasons McGeorge Bundy illustrates, that number is pretty low. The NRDC ten years ago created a report that estimated we needed about 51 warheads to destroy 25% of Russia's population, and about 368 to destroy 25% of China's population.

A nuclear arsenal of 311 warheads
A nuclear arsenal of 311 warheads would still be less than Israel's stockpile. Oh wait, I forgot, Israel has never confirmed or denied possessing nuclear weapons.
311 better than the alternative
I'm curious as to how Professors Schaub and Forsyth arrived at 311 as the magic number. And how is this number compatible with preserving and expanding U.S. national interests?
The op-ed is a well-reasoned piece nonetheless; it's very hard to find former military men who are supportive of non-proliferation in the American nuclear arsenal, not to mention those in the military establishment who speak on behalf of weakening the value of nuclear weapons in U.S. national-security policy. The fact that the recommendations are directly contradictory to current thinking in the U.S. Military and Bureaucratic establishment demonstrates how controversial this argument is to people serving in the U.S. Government.
But it's a debate we need, and a viewpoint that I hope academics, practitioners, generals, and politicians embrace further. The bottom line is that the United States has the most sophisticated, well-trained, and technologically superior military in the world (although the military is stretched pretty thin nowadays). Possessing 1,550 nuclear warheads is a figure that is still extraordinarily high, given the the type of world we are living in.
2,000 nuclear weapons may have been useful if conventional warfare and great-power rivalry still dominated the strategic environment (and I say "may" because 2,000 nukes could destroy the planet many times over). But the threats prevalent in the 21st century are much different than the ones the United States and its allies were facing in the 20th. Proxy warfare, terrorism, insurgency, and rogue regimes cannot and will not be contained using weapons-of-mass-destruction. Imagine trying to defeat Al'Qaeda by bombing them into submission....it can't be done. Terrorists are spread out and difficult to track, and counterterrorism can only be implemented successfully through a combination of tools at the state's disposal; domestic law enforcement and intelligence sharing for example.
There are, of course, some downsides to the Schaub and Forsyth argument. 311 nukes is still 311 more than 0. And I suspect that their study won't make much of a difference anyway (Washington hates change, because accepting change requires politicians to accept fault). But the 311-nuke plan is still much better than the alternative...a large and stagnant arsenal that provides other states with a much needed excuse to develop their own nuclear weapons (uh-hum...Iran and North Korea anyone?).

Similar to Current Chinese ICBM Force
It is interesting that Bundy's comment pretty much parallel's the current Chinese ICBM force of some 20 missiles. Assuming that some missiles would always be down for maintenance and repair, they could likely field 15 missiles on any given day. Assigning 1.5 missiles to any given target city (they're almost assuredly counter-value rather than counter-force weapons) means the Chinese could address 10 urban areas on any given day - or a "disaster beyond history" as Bundy says.
They do the math in the op-ed piece.
100 ICBM + 192 SLBMs (8 subs x 24 missiles) +19 B-2s = 311
We've known that we didn't need that many by the late fifties. It was really more of a pissing match with the Soviet Union*.
*That is the perfect description for what it was, I stand by it.
To start your argument is long, convoluted and could have been made with a third of the text. Second the entire allegory is poor because statistically* you're actually far more likely to be shot if you own a gun. Admittedly that's probably at least in part due to the fact that people who own guns are more likely to live in dangerous neighborhoods or more likely to have those guns used on them in a domestic fights, but the point still stands.
Third, if we actually set up a hypothetical situation where Person A threatens Person B with a gun and Person B pulls out a more dangerous gun, Person A would not think "their gun is more dangerous". Person A would think "they're pulling out a gun, I should shoot first".
Lastly it makes even less sense because, not only do firearms and nuclear weapons belong in completely different situations, they have completely different results. If you're shot with a firearm (regardless of make) you usually have a chance of survival. Even with a shot to the head.If a nuclear weapon is ever used offensively you can be sure that it would be followed by dozens more. A single, small nuclear weapon could effectively destroy a city. Unlike firearms, if even a small nuclear weapon is ever used it would effectively mean that both sides would die with little chance of either side missing.
It would have made much more sense if you had used a situation with two people pressing guns to the others head.
*These statistics are generally publicly available, yet people pay more attention to what a politician says on a screen than checking the numbers.
Can't agree with the view but I don't think it should be attacked either.
This is an interesting post. To start your argument is long, convoluted and could have been made with a third of the text.

All the nukes that you can use
