The U.S. restored formal relations with Iraq in November 1984, but the U.S. had begun, several years earlier, to provide it with intelligence and military support (in secret and contrary to this country's official neutrality) in accordance with policy directives from President Ronald Reagan. These were prepared pursuant to his March 1982 National Security Study Memorandum (NSSM 4-82) asking for a review of U.S. policy toward the Middle East.
One of these directives from Reagan, National Security Decision Directive (NSDD) 99, signed on July 12, 1983, is available only in a highly redacted version [Document 21]. It reviews U.S. regional interests in the Middle East and South Asia, and U.S. objectives, including peace between Israel and the Arabs, resolution of other regional conflicts, and economic and military improvements, "to strengthen regional stability." It deals with threats to the U.S., strategic planning, cooperation with other countries, including the Arab states, and plans for action. An interdepartmental review of the implications of shifting policy in favor of Iraq was conducted following promulgation of the directive.
By the summer of 1983 Iran had been reporting Iraqi use of using chemical weapons for some time. The Geneva protocol requires that the international community respond to chemical warfare, but a diplomatically isolated Iran received only a muted response to its complaints [Note 1]. It intensified its accusations in October 1983, however, and in November asked for a United Nations Security Council investigation.
