 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.The CIA gave the majority of their weapons and finances to Gulbuddin Hekmatyar's Hezb-i-Islami who also received the lion's share of aid from the Saudis.There was recurrent contact between the CIA and Afghan commanders, especially by agent Howard Hart, and Director of Central Intelligence William Casey personally visited training camps on several occasions.
