When in Russia’s thousand-year history has it not felt threatened?
Out of fairness, they had a lot to fear and were invaded constantly in that thousand years. Their culture has not absorbed the reality that having the largest nuclear stockpile of weapons in the world guarantees outside invasion is now an impossibility. That doesn’t mean that Chinese culture creep will not occur but I don’t beleive they look at that as much of a threat. It’s probably easy to see how Mexican’s creeping into the USA didn’t hurt us in the long-run (and I am not talking about the mass invasion that happened in the last few years here at home).
