Russia supplied the Iranians with a ton of materials, know-how, experience, money, technical expertise, maybe some Uranium to start and now? Now they are seeing their 40 year investment in the Middle East go down the centrifugal tubes!
Kick the Russkies clear out of the region.
They’ve kicked themselves out.
They had a beachhead in Syria (and still kind of do) but their stupid frolic and detour in Ukraine has sucked up their entire bandwidth. All the “good” equipment went home to fight.
They also used the ME as a profit center, selling their crap weaponry to Iran. No one will buy S400s again. They’re worthless.
