A Bifurcated Global Nuclear Order

The very destructiveness of nuclear weapons makes them unusable for ethical and military reasons. The world has placed growing restrictions on the full range of nuclear programs and activities. But with the five NPT nuclear powers failing to eliminate nuclear arsenals, other countries acquiring the bomb, arms control efforts stalled, nuclear risks climbing, and growing awareness of the catastrophic humanitarian consequences of nuclear war, the United Nations adopted a new treaty to ban the bomb. Some technical anomalies between the 1968 and 2017 treaties will need to be harmonized and the nuclear-armed states’ rejection of the ban treaty means it will not eliminate any nuclear warheads. However, it will have a significant normative impact in stigmatizing the possession, use and threat of use of nuclear weapons and serve as a tool for civil society to mobilize domestic and world public opinion against the doctrine of nuclear deterrence.
