Nuclear sharing

Nuclear sharing is a concept in NATO's policy of nuclear deterrence, which involves member countries without nuclear weapons of their own in the planning for the use of nuclear weapons by NATO, and in particular provides for the armed forces of these countries to be involved in delivering these weapons in the event of their use.

As part of nuclear sharing, the participating countries carry out consultations and take common decisions on nuclear weapons policy, maintain technical equipment required for the use of nuclear weapons (including warplanes capable of delivering them), and store nuclear weapons on their territory. In case of war, the United States told NATO allies the Non-Proliferation Treaty (NPT) would no longer be controlling.

Of the three nuclear powers in NATO (France, the United Kingdom and the United States), only the United States is known to have provided weapons for nuclear sharing. As of November 2009^[update], Belgium, Germany, Italy, the Netherlands and Turkey are hosting U.S. nuclear weapons as part of NATO's nuclear sharing policy.Canada hosted weapons under the control of the North American Aerospace Defense Command (NORAD), rather than NATO, until 1984, having left the NATO program in 1972 and Greece until 2001. The United Kingdom also received U.S. tactical nuclear weapons such as nuclear artillery and Lance missiles until 1992, despite the UK being a nuclear weapons state in its own right; these were mainly deployed in Germany.
