This issue of Disarmament Forum, “CTBT: Passing the Test”, takes stock of the history and tribulations of the Comprehensive Nuclear-Test-Ban Treaty, and discusses its relevance today as well as practical options for making progress. It starts with an analysis of the original intentions for the CTBT in the broader scheme of disarmament measures, and goes on to discuss how relevant an operative CTBT would be in the current context of nuclear doctrines and developments. The issue also looks at the negative side of the issue in terms of what could go seriously wrong if the treaty does not come into force, for example in terms of decisions to test, whether by existing or aspiring nuclear powers, and the consequences thereof. Three contributions present arguments for different approaches to the current situation: maintaining the moratorium as a de facto CTBT, provisional entry into force, or treaty amendment. The final article addresses CTBT verification and its clear feasibility.
