Solution:NPT designated nuclear weapon states are China, France, Russia, United Kingdom and the United States.The treaty was drawn, drafted and negotiated by the Eighteen Nation Committee on Disarmament, an UN-sponsored organisation based in Switzerland.
On August 6th and 9th,1945, the twin Japanese cities of Hiroshima and Nagasaki were bombed by the United States with a powerful and terrible weapon – The Atom Bomb. The act brought about the end of World War 2, but with a terrible price. Total casualties amounted between 129,000 to 226,000 between the two cities, with countless other injured and suffering from radiation sickness.
The after-effects of the bombings were a serious cause of concern among world powers, along with potential misuse of the weapon. This concern led to calls for a safeguard to ensure a Nuclear Arms Control was in place. Thus it was in 1961, a UN resolution called for a treaty to prevent an arms race for nuclear weapons. This treaty would go on to become the Non- Proliferation Treaty.
