Folks really underestimate how many economic chokepoints there are if the right people feel threatened. I think and hope most Russians know who to blame, but it only takes one person misdirecting their rage to end your life if you're there and look like a target.
I'm sure the "target" understands that perfectly well, and has already taken all necessary countermeasures.
(feel free to replace Jewish with another minority, it's probably also true)
If my understanding is correct, I agree with GP. My understanding of Russian history suggests that Russian politics 101, throughout the regimes, has been to pick (and murder) scapegoats during crises. If you feel that you're a potential target, now is a very good time to make sure that you have a way to survive this.
