The Baruch plan was presented to the UN Atomic Energy Commission, by the US. The plan called for the elimination of nuclear weapons and the implementation of international control over the exploitation of nuclear energy for peaceful purposes. This plan proposed international managerial control or ownership over all potential weapon-related nuclear facilities, as well as inspection of all other atomic energy activities.
The US was to give up its atomic weapons to the new agency after it was set up and functioning. The intrusive supervision mechanism of this plan was unacceptable for Soviet Union and was perceived as an attempt to preserve US monopoly of the weapons. The plan was voted on in the UN Security Council and was rejected.
This was the one and only attempt to create a nuclear free world and get rid of all nuclear weapons all together. During the 1950’s both superpowers were engage in an intense arms race, talks of arm control and reductions resumed only after the Cuba missile crisis.
