TEHRAN—Iran and Russia are forging tighter ties than ever, as their international isolation drives the two staunch American foes toward more trade and military cooperation, alarming Washington.
In July, Iran became the world’s largest buyer of Russian wheat. This month, Russia launched an Iranian satellite into space in a rare success for Tehran’s space program. And last week, Iran’s military hosted joint drone exercises with Russian forces, as the U.S. warns Moscow is preparing to receive Iranian drones for use in the war in Ukraine.
