A joint resolution requesting the President of the United States to negotiate controls upon and the early prohibition of nuclear explosions.

Declares that the President should, at the earliest possible date: (1) endorse and request Senate consent to ratification of the Threshold Test Ban and the Peaceful Nuclear Explosions Treaties; (2) call upon the Soviet Union to agree to reduce the permitted yields of explosions to the lowest verifiable levels; and (3) express to the Soviet Union and to Great Britain the U.S. desire to resume negotiations to conclude a mutual and verifiable ban on nuclear explosions and a moratorium of finite duration on such explosions.
