The New START Treaty between the United States and Russian Federation celebrated its first anniversary of entering into force yesterday. The treaty will cap the strategic deployed nuclear arsenals of each country at 1,550 warheads, a nearly 75% reduction compared with the first START (Strategic Arms Reduction Treaty), which expired in 2009. As of the most recent update to the treaty’s database on Sept. 1, Russia reported 1,566 deployed nuclear warheads and the United States reported 1,790. New START follows a series of similar treaties between the United States and Russia all with the goal of reducing nuclear weapons in both countries and, ultimately, lowering the global nuclear proliferation risk and increasing international security. The obligations laid out in the treaty must be met within seven years of the treaty’s entry into force on February 5, 2010.
