The Islamic Republic of Iran reinforces the destabilizing role of the Islamic State, aka, the Islamic State of Iraq and Syria (ISIS), Daesh in Arabic. Without Iran, the fight against ISIS in Iraq would be easier; but Tehran is supporting radical Shiite militias in Iraq. Tehran has undue influence over the Interior and Human Rights ministries in Iraq, which allow extremist militias to operate in Iraq. Iran's Islamic Revolutionary Guards Corps Qods Force (IRGC-QF) conducts operations in Iraq, contrary to the security of moderate Shiite Iraqi Arabs as well as moderate Sunni Iraqi Arabs. The IRGC-QF is a growing threat to moderate Shiite Iranians—the Peoples' Mojahedin Organization of Iran (PMOI)—held in prison-like conditions in Camp Liberty, Iraq, at the behest of Tehran.
