NSSM 200, also known as National Security Study Memorandum 200, is a policy document that was produced by the United States government in 1974. The memorandum was created under the direction of National Security Advisor Henry Kissinger during the presidency of Richard Nixon. The purpose of NSSM 200 was to evaluate the population growth in developing countries and its potential impact on U.S. national security. The document argues that rapid population growth in developing countries could lead to instability, political unrest, and increased demand for resources. It also suggested that population growth could create a breeding ground for communism and increase the likelihood of conflict.
