When the U.S. signed the Nuclear Non-Proliferation Treaty, we committed to reducing our stockpiles of nuclear weapons. Our promise was part of a global bargain designed to encourage other countries to abandon or forgo the development of nuclear weapons. We have not lived up to our commitment. Instead we continue to maintain nuclear arsenals that serve no meaningful military purpose. The Bush administration’s determination to build a new generation of nuclear weapons, despite bipartisan opposition from Congress, further undermines this bargain, and sends the wrong message to the international community. Continued nuclear weapons production encourages a new arms race as other countries inevitably attempt to catch up.
