Although originally conceived as international measures to reduce the dangers posed by the former Soviet Union's cold war arsenals, Cooperative Threat Reduction is increasingly being adapted to fit the new priorities of non-proliferation and counter terrorism. Considerable experience of implementing CTR has already been accumulated. The political prospects for developing effective CTR are currently favourable and lessons from the political, legal and financial sphere need to be distilled to form the basis for future activities in Russia and elsewhere. The role played by different types of threat reduction measure and the institutional settings in which they have been carried out are examined as well as project management and implementation to identify patterns of successful experience.
