So once again we are in a "war of ideas". I hope we do not face a "new iron curtain" as you say, that would indeed be a shame.
I held so many hopes for the Russian people but foolishly thought they had escaped the prisons of thought that might bind them. So many outstanding people, some of the best writers, mathematicians, and scientists, generations of civilization and a history worth mining for gems.
I now see more clearly that the Russians (and other peoples in that region of the Earth) are neither Western nor Eastern in thought but have their own very different perceptions of the world. And unfortunately many of them seem to suffer an undeserved diminished sense of self-worth and a desire for recognition (some call it "thymos") that is perceived as not forthcoming from foreigners, whether truly present or not.
I have always believed that any Russian or "Eurasian" (if I may use that term to denote the broader groups of peoples in the region) person was as worthy or better, good or bad, strong or weak, kind, and good ... as any person whatsoever. But I fear b/c of the West's indifference and yes, the West's negligence of these peoples after the breakup of the Soviet Union, we have, as a group, not sufficiently shown the respect that is due them. We needed a "Marshall Plan" for the fall of the Soviet Union, if only to offer it.
In general the method works, there were(are) deep economic ties growing between germany and russia for example to mutual benefit. And those sectors are devastated because of the war and were really not in favour of it.
But Russia is a bit bigger than slovakia for example, so some economic ties were apparently not enough.
Also, most of the russia population received an decrease in living standard after the soviet union fell, so democracy was off with a bad start. When your individual life is shit, it is a comfort knowing you are at least part of something great. The RUS empire. Only, that in reality it is just a brutal, rusty moloch, which more people are hopefully seeing now. And yes, it is tragic. We now have war and even if there will be peace eventually, a new iron curtain with mines will once again divide europe.
