Alternate Title: NSDD 51: U.S. Nuclear Testing Limitations Policy

National Security Decision Directive 51 outlines the U.S. Nuclear Testing Limitations policy. "As a result of the National Security Council meeting of July 19, 1982, on nuclear testing limitations, it has been decided that a Comprehensive Test Ban Treaty remains a long-term U.S. objective, but that in the near term, our priority efforts must be directed toward achieving effective verification measures for the Threshold Test Ban and Peaceful Nuclear Explosions treaties."
