The Nuclear Non-Proliferation Treaty (NPT) opened for signature

During the cold war, the negotiation toward the abolition of nuclear weapons was stagnated. Moreover, the number of countries which sought to acquire nuclear weapons or had potential to produce nuclear weapons increased. Thus, it is believed that the prevention of spreading nuclear weapons leads to abolish nuclear weapons. NPT opened for signature in 1968 and entered into force in 1970. The three pillars of NPT are nuclear non-proliferation, nuclear disarmament and peaceful use of nuclear power.
