Toppling the regime also demands breaking up the forces that suppress Iranians, including the Islamic Revolutionary Guard Corps and the notorious Basij militia. The Pentagon’s air campaign aims to weaken these groups by striking their headquarters, command posts, armories, and communication nodes, but it’s unclear whether this will be enough to undermine the forces that prop up the regime. Unless U.S. and Israeli air attacks can isolate and disorient these forces by cutting them off from their command and control, this air campaign will not be sufficient.
