Nuclear sharing

Nuclear sharing is a concept in deterrence theory in which a nuclear-armed country deploys nuclear weapons on the territory of a country that does not possess nuclear weapons and extended its nuclear deterrent to that country. Nuclear sharing typically also involves joint planning and training processes for potentially using them, going beyond nuclear stationing or nuclear basing, which refer to a nuclear-armed country’s deployment of nuclear weapons on foreign soil without an operational role for the host country’s military and government.
