Dec. 27 - On Dec. 22, the United States Senate approved the New Strategic Arms Reduction Treaty (New START) between the United States and the Russian Federation. The treaty stipulates that each country will have no more than 1,550 strategic nuclear warheads and 700 launchers deployed within seven years, and also provides for the resumption of on-site inspections. Secretary of State Hillary Clinton hailed the Senate's actions, saying "A responsible partnership between the world's two largest nuclear powers that limits our nuclear arsenals while maintaining strategic stability is imperative to promoting global security."
