Obama is talking about non-proliferation of nuclear weapons. Thank goodness we finally have someone smart in the White House:
Mr. Obama said that his administration would “reduce the role of nuclear weapons” in its national security strategy, and would urge other countries to do the same. He pointed to the agreement he reached last week with President Dmitri A. Medvedev of Russia to begin negotiations on reducing warheads and stockpiles, and said the two countries would try to reach an agreement by the end of the year. He also promised to aggressively pursue American ratification of the Comprehensive Test Ban Treaty, which in the past has faced strong opposition in Congress.
