Not by NPT alone: The future of the global nuclear order

ABSTRACT The nuclear Non-Proliferation Treaty (NPT) constitutes just one component of broader arrangements that provide global nuclear governance. In recent decades, the other props in the global nuclear order beyond its nonproliferation elements have been eroding, thereby putting more weight on the contributions of the NPT and other aspects of the nonproliferation regime. Unfortunately, recent progress in building up the NPT-based nonproliferation regime seems also to have halted. This article outlines the elements of the global nuclear order and identifies signs of erosion in that order. It discusses whether a greater commitment to nuclear disarmament might help counter that erosion and highlights the underlying cognitive dimension of efforts to avoid nuclear war.
