The Quds Force that Soleimani helmed is the tip of the spear in Iran’s efforts to subvert American, Israeli and Western influence in the Middle East and to buttress Iran’s hegemonic ambitions. The Quds Force offers ideological, financial, and material support, as well as training, for Iranian proxies, which have enabled Iran to establish spheres of influence throughout the region, including in Iraq, Afghanistan, Syria, Lebanon, Yemen, Saudi Arabia, Bahrain, and the Palestinian territories. Through the Quds Force, Iran effectively controls a transnational foreign legion of proxy forces subservient to its foreign policy objectives and willing to operate in whichever theater Tehran orders them to.
As head of the Quds Force, Soleimani was one of the most powerful Iranian regime figures and arguably the individual most responsible for the destruction, destabilization, and inflammation of sectarian tensions that Iran has sown throughout the Middle East in pursuit of regional domination. Under Soleimani, Iran amassed influence in a swathe of territory stretching from Afghanistan to Lebanon and Syria, creating a “Shia crescent” that functionally acts as a land bridge linking Tehran to the Mediterranean, enabling Iran to more efficiently and lethally arm its proxies. Since turning the tide of the Syrian civil war decisively in favor of its client, the Assad regime, Iran has increasingly sought to entrench itself militarily within Syria, creating a base from which to project power into the Levant and encircle and threaten Israel.
