The nuclear implosion in Hiroshima and Nagasaki gave birth to a new weapon and changed the conventional nature of strategic calculations. This new weapon played the main role in contemporary strategy after the World War II. The destructive nature of this weapon and strategic spill-over resulting from entering this weapon to a region has made the owners of this weapon to try their best to abandon others to obtain this weapon.
Conversely, states without this weapon initiated efforts aimed at disarmament and destruction of this weapon. That’s why the term disarmament is almost as old as the term nuclear weapon.
Will nuclear disarmament really possible or remain as a utopian ideal? The current article aims to study the nuclear disarmament theoretically and to see what theories of international relations are appropriate to analyze the nuclear disarmament. Giving some evidences of international efforts and current trends, the author will consider the possibility of success for these efforts.
