I agree, and I'd also add New Zealand and probably South Africa to the list of places that would allow Russian refugees to settle.
The question that would have to be asked here in this scenario though is how well such people will be able to contribute to their new homes with the mental health issues that will be so, so prevalent here. I agree fully that there will be refugee movements of a truly massive scale, but how easy will these people find establishing new lives in France or Germany or Canada or the United States or Australia knowing the demons that will surely torment so many of them?
And what will people make of those involved in the crimes of the Barkashov and Anpilov regimes? Even today many from Serbia still face disdain from others for the actions of Milosevic and his minions, and those bastards didn't get up to much more than a fraction of the Dirlewanger-grade depravity of these guys. Will these people be welcome in their new homes, or will there be a large number of others who think "Russians, filthy fucking animals, I want nothing to do with them"?
