Nukes in the next administration
Yesterday, the Brookings Arms Control and Non-Proliferation Initiative held an event discussing how the next presidential administration should approach nuclear arms control and deterrence. Brookings scholar Michael O’Hanlon interviewed fellow Brookings scholar Steven Pifer on his recent report about this topic.
Although there are many nuclear states that we need to keep an eye on, Pifer explained,the primary concern for the next administration should be Russia due to their large arsenal and our quickly deteriorating relationship. Russia has also expressed a desire to modernize their arsenal, and the US needs to keep a close eye on that. Given that Russia and the United States have more warheads than any other country, if the two great nuclear powers reach a strong reduction agreement, it will serve as an example for the rest of the world. Additionally, the New START treaty will expire in 2021—the next administration needs to take a long, hard look at the existing treaty and decide whether they want to renew it or renegotiate the terms.
In many respects, conventional weapons have become almost as deadly as traditional nuclear warheads; perhaps conventional arms reduction should be considered as well. Pifer recommended that while the US should maintain the existing defense triad of submarine launched domestic missiles, ICBMs and bombers, the next president should consider reducing their numbers. Maintaining all these warheads is very expensive. The US doesn’t really need 700 deployed missiles—they could get by on 550 and save. In fact, nuclear parity with Russia is not a strategic concern but rather a political one. Having as many or more warheads than Russia reassures US allies that the United States is capable of defending them and gives the US a better position at the negotiating table.
The US has pledged to use its warheads if the homeland or one of its allies is attacked with nuclear weapons, but foreign allies are nervous that Washington will only use its nuclear capabilities if attacked at home. Indeed, Pifer said, no president would be willing to risk Chicago for a small city in South Korea. Current US policy also gives room for US enemies to attack the homeland with conventional weapons without fear of nuclear reciprocation. Pifer believes that despite these issues, the policy contributes to nuclear deterrence and can be strengthened by improving communication with allies that depend on the US for nuclear security.
Pifer advises that the US should push hard for other nuclear states to sign the Comprehensive Test Ban treaty. The US has no need for further testing at the moment, since it conducted so many nuclear tests in the second half of the 20th century. In fact, the US conducted more tests than the rest of the world combined. As a result of these extensive tests, US knowledge about nuclear weapons far surpasses the rest of the world. Therefore, by encouraging others to sign the treaty, the US keeps the knowledge it gained from its own nuclear tests while ensuring that the rest of the world never catches up.
