The US Nuclear Posture Review and the NATO allies

The 2001 US Nuclear Posture Review called for reducing operationally deployed US strategic nuclear warheads by almost two-thirds over the decade ending in 2012; emphasizing the development and/or improvement of capabilities other than nuclear forces, including missile defences, non-nuclear strike forces, and a responsive infrastructure; and placing nuclear and other capabilities within the framework of new concepts such as dissuasion and capabilities-based planning. The reductions foreseen in the NPR furnished the basis for the May 2002 Moscow Treaty. Allied observers have welcomed this treaty as a political substitute for the ABM Treaty and START negotiations, but have found it disappointing as an arms control measure. While allied observers have expressed reservations about combining nuclear and non-nuclear strike forces in a single notional leg of the 'New Triad' and about increasing readiness for possible nuclear testing, they have endorsed unprecedented steps in the defensive area, notably with respect to ballistic missile defence. Some new US concepts have been relatively uncontroversial because they represent continuity, but others (such as dissuasion and deterrence by denial) have evoked scepticism.
