The Clark Amendment was an amendment to the U.S. Arms Export Control Act of 1976, named for its sponsor, Senator Dick Clark (D-Iowa). The amendment barred aid to private groups engaged in military or paramilitary operations in Angola. Even after the Clark amendment became law, however, then-Director of Central Intelligence, George H. W. Bush, refused to concede that all U.S. aid to Angola had ceased. According to foreign affairs analyst Jane Hunter, Israel stepped in as a proxy arms supplier for the United States after the Clark Amendment took effect.
