In 2020, the participants in the 1970 Treaty on the Non-Proliferation of Nuclear Weapons (NPT) will congregate for the treaty’s 10th review conference. Which means that it may be a good time to re-examine the relevance of the NPT, and even consider the idea of dropping this treaty in its entirety, in favor of the new kid on the block: the 2017 Treaty on the Prohibition of Nuclear Weapons, also known as the Ban Treaty. At the risk of grossly oversimplifying, one treaty seeks to stop the further spread of nuclear weapons, while the other goes further and seeks to get rid of them entirely. This difference is reflected in their formal titles. Why should we ditch the former in favor of the latter? To answer that, let us look at history.
