vital to its national security. Qassem Soleimani, the leader of the IRGC’s elite Qods Force, Mohammad Ali Jafari, the head of the IRGC, and most of the other top leadership of Iran’s armed forces are hardened veterans of the 1980-1988 Iran-Iraq War. That conflict and more recent attacks carried out by Syria-based Sunni jihadists in Iran are seared in these officers’ collective memories. They view Salafi-jihadi extremism as an existential threat to Shiite Iran, and while there are many in Iran who dislike Iran’s adventurism abroad and have even protested it, there are also many Iranians who view Tehran’s involvement in Syria, Iraq, and Lebanon as necessary to keep fighting outside Iran’s borders. Indeed, this mentality is not so different from that of the George W. Bush administration, which invaded Afghanistan and Iraq ostensibly to deter new threats to the US homeland.
