Different international locations gave up their nuclear weapons, or applications to develop them.
Some successes
There have been main achievements in stopping international locations from gaining nuclear weapons and dramatically lowering nuclear weapon stockpiles because the Chilly Battle.

Beginning within the late Sixties, international locations agreed to greater than a dozen legally binding agreements, referred to as treaties, that restricted new international locations getting nuclear weapons and prohibited nuclear weapon testing, amongst different measures.
However they haven’t decreased the variety of nuclear weapons with brief vary missiles.
No agreements cowl these weapons, which may additionally trigger widespread destruction and deaths. Russia’s short-range weapons may rapidly destroy a lot of Europe.
