Tehran and Moscow have grown their military-to-military relationship over the course of Russia’s war in Ukraine, which has pitted Russia in a corner on the global stage. Iran has been one of the few countries to come to Russia’s aid, having provided them with hundreds of one-way attack drones that Russian forces have used to target Ukrainian energy infrastructure over the course of the war.
