The U.S. and Russia reached a breakthrough agreement Wednesday for a historic treaty to reduce the nuclear arsenals of the former Cold War rivals, the most significant pact in a generation and an important milestone in the decades-long quest to lower the risk of global nuclear war.
The agreement would still leave each country with a large number of nuclear weapons, both deployed and stockpiled.
Norris, the nuclear weapons expert, and Hans M. Kristensen of the Federation of American Scientists, estimate that the U.S. has 2,150 deployed strategic nuclear weapons and the Russians have about 2,600. The U.S. has another 2,600 warheads held in reserve, plus 500 non-strategic nuclear weapons, by the two experts' estimate. Another 4,200 retired U.S. strategic warheads are awaiting dismantlement.
