In the first major foreign-policy speech of his tenure, President Barack Obama told a wildly cheering audience in Prague that the United States would commit itself to "a world without nuclear weapons" and then described in detail the "trajectory" required to get there. In the almost three years since that euphoric moment, the Obama White House has done what it so often does -- forthrightly acknowledge the complexity of its visionary goal, issue nuanced documents that compromise that goal even while reaffirming it, and accept half-measures, then quarter-measures, in the face of utterly unreasonable partisan opposition, surrendering more than planned to get less than expected.
Obama now has the chance -- perhaps his last chance -- to finally make good on his Prague pledge. He has ordered a review of the U.S. strategic arsenal, to be delivered to him in the coming weeks. The president must decide how many nuclear weapons the United States really needs. Arms control advocates think that this time, finally, Obama will grasp the nettle and accept that the country needs far fewer deployed warheads than the 1,760 or so it now has. I hope he does. But the mottled history of the last three years should give any disarmament advocate pause.
According to the extraordinarily ambitious strategy Obama laid out in Prague, the United States would adopt a new policy to "reduce the role of nuclear weapons in our national security strategy," pursue arms reduction in treaty negotiations with Russia, pass the Comprehensive Test Ban Treaty and the so-called Fissile Material Cutoff Treaty to control the production of enriched uranium and plutonium, and strengthen the provisions of the Nuclear Non-Proliferation Treaty.
Of all these measures, the only one wholly within Obama's own powers was the new policy statement, to be embodied in a document called the Nuclear Posture Review. I followed this debate closely throughout 2009; then, administration officials told me that the document would furnish a clear "narrative" of a fundamental, directional change toward eliminating nuclear weapons. Advocates inside the administration hoped that the new document would change "declaratory policy" to stipulate that the United States would only use nukes against a nuclear threat rather than, for example, against a rogue state or a terrorist group that it feared might obtain weapons of mass destruction (as current policy now foresees); that it would end the terrifying but archaic Cold War requirement that hundreds of warheads be available for launch "on warning"; and that it would eliminate one leg of the nuclear "triad" of bombers, missiles, and subs (probably bombers). None of those things happened. As I noted at the time, even Sam Nunn, the hawkish former U.S. senator, said that he was "disappointed" with Obama's caution and specified that the unwillingness to "de-alert" the nuclear force "went beyond what I thought was rational."
The Nuclear Posture Review, published in April 2010, was blunted by skeptics in the Pentagon and perhaps the White House, as well as by opposition in the nuclear laboratories. The disarmament negotiations over the New START agreement, however, faced external resistance -- first from the Russians, who dragged out the talks over months, delaying Obama's planned trajectory, and then from Senate Republicans, many of whom treated the modest agreement to limit each side to 1,550 deployed strategic warheads as a radical act of unilateral disarmament. To win them over, the administration had to promise to make exorbitant investments in the nuclear labs in Los Alamos and elsewhere.
We live with that decision today: The Energy Department's 2013 budget includes a 5 percent increase for refurbishment of the equipment that produces warheads and their nuclear "pits," upkeep of the weapons themselves, and training for nuclear scientists and the like, at a time when discretionary spending is frozen. Over the next decade, the United States is now projected to spend over $180 billion on nuclear modernization.
