I got to know more about Dmitry from his first appearance in a podcast here about the crisis in the Ukraine and have since checked out his latest takes off and on. In this case, his analysis and perspective shine through again.
However, Dmitry's conclusions and plans are somewhat particular. I guess that it'd make sense to find sanctuary in Russia for a Russian in the chance of a global socio-economic collapse. Russia is a resource rich country with a sizeable population that's already been stressed in the last few years by the sanctions. So, on one hand, it can provide a reasonable economy of scale and division of labor just considering its internal market and be able to do without foreign trade for some time, I suppose. On the other hand, a crisis has just been inflicted on it and led it to react and, say, plug the holes and mend the cracks on the dam of its economy. Methinks therefore that Russia is not a bad place to weather out a global crisis, provided that it doesn't escalate to to a global war.
If the coming crisis does escalate to a global war, Russia would be a primary player in it, for better and for worse. Its military capabilities allow it to project influence and to defend itself, both necessary traits considering its geopolitical position on the atlas. However, they also make Russia a primary target.
Indeed, unlike Afghanistan, Iraq, Libya, Syria or Yemen, an attack to Russian interests would result in retaliation on the attacker's interests and an attack against Russians would result in retaliation against the attackers. Still, the end result would be a bloodbath and the loss of millions of souls.
From this perspective, I'd prefer S. America, which is surrounded by thousands of miles of oceans that deprive it of any strategic value. Some of the countries in the continent also enjoy plentiful resources and advanced economies to survive on their own, but in peace with their immediate and distant neighbors. No need to mention the much more favorable climate and abundant crops. However, their worst enemies are found internally, in their utterly corrupt political and economic agents as well as in their rampant criminal class. But, like Dmitry, that's me, a Latin.
PS: Dmitry is brilliant in his analysis of the facts, especially involving his homeland, but can sometimes be a bigoted misanthrope too. So keep what is good from what he offers and trash what is bad.
