Extended deterrence consists in extending the logic of deterrence to a third party, that is, persuading a potential adversary that the costs of attacking a protected country would exceed its benefits through a security guarantee given to the protected party. To a large degree, it stems from any form of military alliance between a stronger country and a weaker one—although alliances per se generally include a mutual defense commitment, which is not a prerequisite to extended deterrence.

Abstract:
Ever since its entry into force in 1970, the nuclear Non-Proliferation Treaty (NPT) has been the cornerstone of the fight against the spread of weapons of mass destruction (WMD). At the same time, it is one of the most universal international legal instruments, with 189 states parties in early 2005 (only India, Israel and Pakistan remain outside the Treaty).
