Good plausible thoughts in your scenario for the most part. Russia just cut off gas to the Ukraine as a pretest to their trying to join the EU.
But I'd say it's reductive to assume China would back Iran in any way. They need the US relationship far more than unity with Iran. China will sit
on the sideline in anything involving the Middle East and watch the active players further debilitate each other for now.
Russia has a love-hate relationship with Iran. They love being paid top dollar for their junk military equipment but don't want to be on the wrong
end of the Middle East struggle. The Saudis want Iran knocked out, as do the US and almost everyone else. Russia barks loud, but with their military
equipment and infrastructure in tatters, cannot even consider a military confrontation with the US.
Iran has overconfidently believed they will spearhead an Islamic Revolution and overthrow incumbent corrupt Sunni regimes backed by the West. But so
far only Syria, Lebanon, and rogue states like Venezuela have come on board.
Iran may win some PR points in skirmishes like Gaza, but are not anywhere in position to engage one-o-one in a knock down drag out war.
What's happening now is realignment rather than a prelude for war.
