Summary: The Bush administration has adopted a misguided and dangerous nuclear posture. Instead of recycling antiquated doctrines and building a new generation of warheads, the United States should drastically reduce its nuclear arsenal, strengthen the international nonproliferation regime, and move toward the eventual elimination of nuclear weapons.

Since the demise of the Soviet Union, Washington's strategic thinking about nuclear weapons has evolved in dangerous and unwise directions. In January 2002, the Bush administration announced a new nuclear posture, which it reiterated in 2006. But instead of doing what it claimed it would do -- adapt American nuclear strategy to the realities of the twenty-first century -- the administration has focused on addressing threats that either no longer exist or never required a nuclear response. Rather than protecting the United States, this posture constitutes a danger to U.S. security.
The risks posed by nuclear weapons today are daunting, but rarely in the same ways that they used to be. As the nuclear club has expanded since the end of the Cold War, so have the dangers posed by the possibility of an inadvertent release of nuclear weapons, a regional nuclear conflict, nuclear proliferation, or the acquisition of nuclear weapons by terrorists. At the same time, the military utility of nuclear weapons for the United States has decreased dramatically. Russia, the successor to the Soviet Union, is no longer an adversary, and the United States, now the world's unchallenged conventional military power, can address almost all its military objectives by nonnuclear means. The only valid residual mission of U.S. nuclear weapons today is thus to deter others from using nuclear weapons. Given all this, it does not make sense for the United States to maintain a nuclear weapons stockpile of close to 10,000 warheads -- many of them set on hair-trigger alert -- and to continue to deploy nuclear weapons overseas.
An effective nuclear policy would take into account the limited present-day need for a nuclear arsenal as well as the military and political dangers associated with maintaining a massive stockpile. Building a new generation of warheads, as the Bush administration has proposed, would only compound these risks further.
Nuclear weapons cannot be uninvented, but as former Secretaries of State George Shultz and Henry Kissinger, former Defense Secretary William Perry, former Senator Sam Nunn, and the outgoing British foreign secretary, Margaret Beckett, have recently argued, a shift in U.S. policy could blaze the trail toward their eventual prohibition. Given that the risks posed by nuclear weapons far outweigh their benefits in today's world, the United States should lead a worldwide campaign to de-emphasize their role in international relations.
THAT WAS THEN
During the Cold War, the United States' policy of deterrence was designed to convince the Soviet Union's leaders that the assets they valued most highly, including their population, armed forces, and industrial centers, risked destruction if Moscow launched a major attack on the West. Estimates of the nuclear forces Washington needed to make such a threat credible -- that is, what forces it would need to be able to retaliate after withstanding a nuclear first strike -- differed widely. Some analysts were optimistic and thought a limited arsenal would suffice; others were pessimistic and sought to establish unchallengeable nuclear primacy. These debates, coupled with parochial bureaucratic pressures from the U.S. Air Force, led ...
