Disarmament Diplomacy, Vol. 79
Do the nations that belong to the nuclear Non-Proliferation Treaty (NPT) have a right to withdraw from it at any time they wish and for any reason? This is a key question when considering international legal constraints on nuclear proliferation, and one that will confront the States Parties when they meet in New York on May 2. This article argues that the NPT and the United Nations Charter provide limits on the right of withdrawal from the treaty by authorising the UN Security Council to take action against NPT withdrawals that could lead to threats to international peace and security.
