Maybe it's not 4d chess and instead it's just regular chess and doing things like taking on Iran is just unfortunately something we have to do.

> Just when Russia (a petro state) desperately needed and economic shot in the arm.

Like when you say things like this it doesn't make any sense. Trump stopped Venezuelan support of shadow fleet tankers, he has increased sanctions on Russia, and you can certainly argue if you want that the Iran was isn't going according to Trump's plans (which is ego of course has a substantial impact) but Iran was providing military support to Russia and also helping them evade sanctions.

So can you please point to the exact mechanism you are referring to that's giving Russia an economic shot in the arm? Because from what I can tell Russia isn't receiving any economic shots in the arm and instead is facing increased sanctions and better enforcement of those sanctions.
