Alternate Title: NSAM 205: Nuclear Testing

This Nuclear Security Action Memorandum (NSAM) outlines a process for review of the 1962 atmospheric test series and their effect on the relative balance between U.S. and Soviet capabilities, and call for a Committee which "should address itself not only to the specific question of what has been learned by testing in terms of the design of nuclear weapons, their effects, and defense against them, but also to the broader question of the military significance of what has been learned and its probable effects on the present and prospective military balance between the U.S. and the Soviet Union."
