The Islamic Republic founded and sponsored the Lebanese group known as Hezbollah; its leaders were followers of Khomeini. The creation of Hezbollah, and its funding from Iran, was in response to the Israeli occupation of Lebanon. Since then, Hezbollah has served as both an ally and a surrogate for Iran during its conflict with America and Israel. Author Olivier Roy describes the Islamic Republic's as having "lost most of its allure among non-Iranian Shia's," giving as examples the 1995 house arrest in Qom of the two sons of Grand Ayatollah Shirazi, spiritual leader of the Bahraini Shia; and the close cooperation between the Afghan Shia party Wahdat and the U.S. Army after November 2001.
