Peace Corps Library writes "The United States and Russia, seeking to move forward on one of the most significant arms control treaties since the end of the cold war, announced that they had reached a preliminary agreement on cutting each country's stockpiles of strategic nuclear weapons, effectively setting the stage for a successor to the Strategic Arms Reduction Treaty (Start), a cold war-era pact that expires in December. Under the framework, negotiators are to be instructed to craft a treaty that would cut strategic warheads for each side to between 1,500 and 1,675, down from the limit of 2,200 slated to take effect in 2012 under the Treaty of Moscow (PDF) signed by President George W. Bush. The limit on delivery vehicles would be cut to between 500 and 1,100 from the 1,600 currently allowed under Start. Perhaps more important than the specific limits would be a revised and extended verification system that otherwise would expire with Start in December. The United States currently has 1,198 land-based intercontinental ballistic missiles, submarine-based missiles and bombers, which together are capable of delivering 5,576 warheads, according to its most recent Start report in January, while Russia reported that it has 816 delivery vehicles capable of delivering 3,909 warheads. 'We have a mutual interest in protecting both of our populations from the kinds of danger that weapons proliferation is presenting today,' said President Obama."
