Nuclear disarmament refers to the efforts of political movements and states to reduce or eliminate nuclear weapons with the goal of achieving a world free of nuclear weapons. Whether this is possible given the apparent utility of nuclear weapons for (hypothesized) deterrence or would affect the likelihood of war waged with other weapons is unclear.
After the fall of the USSR, the republics of Belarus, Ukraine and Kazakhstan surrendered the Soviet nuclear weapons stationed on their territory to Russia. Many nonproliferation and disarmament treaties have been signed as well, which have helped the cause to some extent. However, the only country that has ever fully dismantled its nuclear arsenal is South Africa.
