Russia only cares about Russia.
Russia wants a destabilized middle east. They are sitting on huge oil reserves and they need the hard cash that comes with them. If Iran keeps going until they get bombed, and Iran can get off a few decent shots back, then Russia wins big-time.
That is ALL Russia cares about.
That’s the ulterior agenda of the Russkies.
If the Straits are closed by Iran and gas prices sky rocket Russia will be sitting pretty.
You are spot on with your conclusion that Russia WANTS an unstable Meddle East, one that would seriously impact the transport of oil from that region, as that would leave Russia, a large oil producer and exporter itself, with a windfall as the market would look to Russia to cover the deficit. Russia would make out like a bandit.
