National Security Study Memorandum 200 is a document that was written in 1974 by Henry Kissinger, who was the United States Secretary of State at the time. The document said that the United States should use its foreign aid resources to encourage developing countries to control their birth rates and population growth. The US wanted to ensure that these countries did not become a burden to the US and that the US could help them become better countries. The document said that the US should give money to these countries to help them have better food, health care, and education so that they could be better able to take care of their citizens. This would help the countries become better countries and not be a burden to the US.
