WASHINGTON - A US government document reveals that the Obama administration is planning to cut the US nuclear stockpile by up to 40 percent by 2021.
In May the administration said that it had 5,113 nuclear warheads in its stockpile.
The new document says the administration would like to reduce that number to a range of 3,000 to 3,500.
The document was presented to Congress in May and posted Tuesday on the websites of the Federation of American Scientists and the Union of Concerned Scientists.
