The list below features all nations who own stockpiles of Nuclear weapons around the World. Whilst this list concerns only the nations who own the stockpiles, sometimes nations could have some of their warheads deployed in other nations under ‘nuclear sharing’ deals – most notably, the United States, who have nuclear weapons deployed in Belgium, Germany, Italy, Netherlands and Turkey (150-200 nuclear warheads in total).
The World’s overall nuclear arsenal is held by a handful of states, however the vast majority of those bombs have always been owned by Russia and the United States alone. Between them, they have 20 times as many nuclear weapons, as the rest of the World, combined. They could both easily destroy the entire planet – in a matter of seconds – many times over.
The following list is included, on a yearly basis, as part of the SIPRI Yearbook, by the Stockholm International Peace Research Institute (SIPRI) – a publication which outlines data and analysis in the areas of national security, conflicts, military spending, armaments, non-proliferation, arms control and disarmament.
