> Russian economy is booming actually

Mostly the military, from what I hear. The rest of the economy is in shambles [1].

No matter what: once the war in Ukraine is over by whatever solution, it's going to get nasty. Either Putin (or, more likely, his successor - the dude is old and it's by far not sure if he will be able to stay in power should the war end up bad for Russia) manages to turn around the economy once again from producing tanks and other instruments of war to a regular economy, or they'll keep it that way... and attack another country with all that firepower.

There's a trickle down effect from it, same as with all massive government spending. Those factory workers who now have cushy jobs with large paychecks assembling tanks and cruise missiles then go and spend that money on other things.
