The Status of Norms against Nuclear Testing

Can the current global moratorium on nuclear weapon testing survive the May 1998 tests by India and Pakistan and the refusal of US Senate leaders to permit consideration of the Comprehensive Test Ban treaty (CTBT) by the Senate? If nuclear testing resumes by India or Pakistan - or by Britain, China, France, Russia, or the United States - will it be condemned by most of the world as if an international norm against testing was already in effect? What will be the likely consequences for nonproliferation if tests resume? This article seeks to show that there are norms operating against nuclear testing even though the CTBT has not been ratified, and that renewal of testing would have widespread consequences.
