The ratification of New START appears to be the high-water mark for arms reduction efforts, with Russia and the United States still apparently far apart on a negotiating mandate for a next round. And with the exception of the nuclear security summit process, progress on the other initiatives laid out by President Obama in Prague in April 2009 has been slow going. The nuclear abolition movement, despite statements from very prominent former U.S. officials, has failed to garner sustained international support. There has been no progress on FMCT negotiations and CTBT ratification in a number of key states. Do the governments of China and Russia embrace the logic of the Prague agenda and share an understanding of strategic stability with the United States? What evidence exists that other leaders share Obama’s interest in this agenda? What can be done to reinvigorate reciprocal progress on nonproliferation and disarmament?
