(CNN) -- Airstrikes against ISIS militants are a "psychological operation," not a military one, Iranian President Hassan Rouhani told CNN's Christiane Amanpour in an interview that aired Friday. "It is a common threat for all of us," he said. "And this requires a unison effort from all of us." "We need a vast campaign of operations ... the aerial bombardment campaign is mostly, I would say, a form of theater, rather than a serious battle against terrorism." Iran and the United States have found their foreign policies surprisingly aligned in the past several months, as both try to beat back the advance of the Sunni extremists that have gained a foothold in Iraq and war-torn Syria.
