Nuclear sharing

Nuclear sharing is a concept in NATO and Russia's policies of nuclear deterrence, which allows member countries without nuclear weapons of their own to participate in the planning, training, and, in extremis, the use of nuclear weapons. In particular, it provides for involvement of the armed forces of those countries in the nuclear sharing arrangements for delivering nuclear weapons in the event of the authorization for their use by the head of state of the nuclear possessor country.

As part of nuclear sharing, the participating countries carry out consultations and make common decisions on nuclear weapons policy, training, and deployment, and maintain technical equipment (notably nuclear-capable airplanes) required for the delivery of nuclear weapons. Some of these states also allow the nuclear weapon state to store nuclear weapons on their territory. In case of war, the United States publicly stated (and the negotiating parties agreed) that the Non-Proliferation Treaty (NPT) would no longer be controlling.^[1]
