Russia is probably one of the best-case scenarios for much of the industrialized world. Russia, after all, at least has ample capacity at home to feed and fuel itself in addition to sufficient nuclear weapons to make any would-be aggressor stop and think (a few dozen times) before launching an assault. In a world of constrained trade and capital, one could be in significantly more dire straits than still having strategic depth plus reasonably reliable food, fuel, and electricity.
