By the early 2000s, cooperation had started to slow down. In 2002, the United States withdrew from the Anti-Ballistic Missile Treaty, a hallmark of Cold War nuclear arms control. There was a rare burst of optimism in 2010 when Washington and Moscow signed the New START Treaty, which further reduced U.S. and Russian nuclear arsenals. Still, the countries retain enormous numbers of the world’s most dangerous weapons: As of January 2015, Russia and the United States had more than 7,000 nuclear warheads each, about 90 percent of world stocks, according to the Stockholm International Peace Research Institute. And those numbers may not go down anytime soon. Russia has made it clear that removing U.S. missile defense weaponry from Europe is a precondition for any talks on a new arms control treaty. The Obama administration has said that is out of the question.
