Democratic congressman Charlie Wilson became obsessed with the Afghan cause, in 1982 he visited the Pakistani leadership, and was taken to a major Pakistan-based Afghan refugee camp to see first hand the conditions and the Soviet atrocities. After his visit he was able to leverage his position on the House Committee on Appropriations to encourage other Democratic congressmen to vote for CIA Afghan war money. Wilson teamed with CIA manager Gust Avrakotos and formed a team of a few dozen insiders who greatly enhanced support for the Mujahideen. With Ronald Reagan as president he then greatly expanded the program as part of the Reagan Doctrine of aiding anti-Soviet resistance movements abroad. To execute this policy, Reagan deployed CIA Special Activities Division paramilitary officers to equip the Mujihadeen forces against the Soviet Army. Avrakotos hired Michael G. Vickers, the CIA's regional head who had a close relationship with Wilson and became a key architect of the strategy. The program funding was increased yearly due to lobbying by prominent U.S. politicians and government officials, such as Wilson, Gordon Humphrey, Fred Ikle, and William Casey. Under the Reagan administration, U.S. support for the Afghan mujahideen evolved into a centerpiece of U.S. foreign policy, called the Reagan Doctrine, in which the U.S. provided military and other support to anti-communist resistance movements in Afghanistan, Angola, and Nicaragua.
