States
Russia
Iran's most operationally aligned major-power partner; supplier of weapons technology and political cover at the UN Security Council.
Role in conflict
Russia and Iran are operationally aligned in Syria, where they coordinated against the anti-Assad opposition for nearly a decade, and the alignment has deepened since 2022 with Iranian drone and short-range missile transfers to Russia for use in Ukraine. Moscow provides political cover for Iran at the UN Security Council and has supplied air-defence components and some advanced military technology. The alignment is closer than the "axis" framing suggests but is constrained by Russia's commitments in Ukraine.
