Either side might miscalculate the stock of arms in the possession of the other side. Moreover, super power might misunderstood the intentions of the other side. Besides, there can be a nuclear accident. Hence both the super powers i.e. U.S.A and U.S.S.R. decided to collaborate in limiting or eliminating certain kinds of nuclear and non-nuclear weapons. In 1961 Soviet Union an United States made a joint statement in general Assembly. Both the countries agreed for negotiation towards total disarmament. Partial Test Ban Treaty (1963) was signed by the foreign ministers of the U.S.A, U.S.S.R and U.K. In 1968 the Non-proliferation Treaty was signed. But India refused to sign thin treaty on the ground that it was discriminatory in nature. The threshold Test Ban Treaty was signed on 3rd July 1974 by the two super powers. After these treaties many more treaties were signed by the two super powers to limit their arms.
