The Treaty on the Nonproliferation of Nuclear Weapons (NPT) is widely credited with contributing to international security through its promotion of nuclear restraint. Whereas almost all states in the international system are members of the NPT, many of these states have not signed on to additional treaties and agreements designed to strengthen the regime. Having already committed to foreswear the possession of nuclear weapons, why would some NPT members avoid taking steps to further the treaty's proclaimed goals? States' affinity to U.S. global leadership explains such variation.

Employing quantitative analysis drawn from an original dataset of nuclear nonproliferation commitment indicators, this project finds a significant relationship between affiliation with the U.S. global order and nuclear nonproliferation regime commitment. The findings suggest that the nuclear nonproliferation regime should be considered part of the U.S.-led order. Ultimately, the regime may falter without superpower backing.
