New START
In March 2010, the United States and Russia reached an agreement to reduce their stockpiles of nuclear weapons. The new nuclear arms reduction treaty (called New START) was signed by President Obama and President Medvedev on April 8, 2010. The agreement cut the number of long-range nuclear weapons held by each side to about 1,500, down from the current 1,700 to 2,200 set by the Moscow Treaty of 2002. The New START replaced the 1991 Strategic Arms Reduction Treaty, which expired in December 2009.
