Steve Coll of The New Yorker lays out Obama's challenge of striving towards nuclear non-proliferation:
"Ronald Reagan, Henry Kissinger, George Shultz, and Sam Nunn are among the Cold War-era defense hawks who have preceded Obama to an embrace of nuclear abolition. Even so, it is commonplace to criticize this vision as naïve, since the goal is unlikely to be achievable anytime soon. This criticism distorts the abolitionist movement’s work; its supporters do not generally waste time on speculative debates about when and how a world containing precisely zero nuclear weapons might eventually be created. Instead, they want to drive down the world’s nine nuclear arsenals to much smaller sizes as quickly as possible—perhaps to the tens or low hundreds of weapons, in the case of the United States—and, while doing so, to make nuclear weapons as illegitimate and impractical as possible."
