Are there other countries beside South Africa that have voluntarily relinquished their nuclear arms?

Yes, Belarus, Kazakhstan and Ukraine. When the Soviet Union collapsed in December 1991, its nuclear arsenal was left scattered over four newly independent countries: the Russian Federation, Belarus, Kazakhstan and Ukraine.

In assuming the USSR’s legacy, including its status as a nuclear weapon state under the 1968 Non-Proliferation Treaty, Russia eventually consolidated all nuclear weapons and delivery systems on its own territory (many were voluntarily destroyed in the process).
