The United States had mixed results at the 2010 NPT Review Conference. On the one hand, it avoided the isolation and criticism directed at Washington in connection with the failed 2005 Review Conference, in large measure because the Obama administration took more congenial positions on a number of nuclear issues. Its cooperation also facilitated the successful achievement of a consensus final document. On the other hand, there was wide resistance to a number of measures for strengthening the NPT system favoured or promoted by the United States, resistance that reveals deep and worrying divisions within the regime.
