Strengthening Threat Reduction

To reduce the risk that nuclear weapons, delivery systems and fissile materials could be acquired by unauthorized state or non-state actors a number of practical measures have been defined to increase their physical security, safeguard against their diversion or misuse and in some cases eliminate them or render them unusable. Many of the international non-proliferation and disarmament assistance measures are intended for implementation in Russia, reflecting the continued legacy of cold war militarization. The G8 group of industrialized states have played an important role in financing threat reduction measures.
