ujm, there were multiple mysterious posters at the beginning of Russian invasion into Ukraine with such views that then disappeared. You got some very chassidishe people not only writing in Yinglish, but having impressive history knowledge correlated to soviet textbooks. I presumed they were part of Russian cyber war where they went into all kind of online publications. Are you their long-term resident and got new orders?
There is more historical anti-semitism in Ukraine (and in Poland, and in Lithuania, and in Germany) than in Russia – for a simple reason: Russian empire did not allow Jews enter it, with few exceptions. Even after Russia conquered Polish areas with large Jewish population, those were limited to beyond the “Pale” – previous borders of Russia (incidentally, “beyond the Pale” is something that applies to your posts too!). As to current population, a large swath of Ukraine is Western-oriented (and many are currently in Europe). They can’t be that antisemitic as they voted for a Jewish comic as President, however assimilated. Russia mostly stayed the same it was under Czars and Commies.
But I will give you. As much as I think it is reasonable for Ukrainian Jews to defend their country against an invasion, it will be reasonable for Russian Jews to defend their country when Chinese attack it. As to participation in an invasion, directly or indirectly, see writings of Abraham Heschel who cryptically writes in 1930s, under Nazi censorship, that Sephardi Jews were prosecuted but avoided being victimizers themselves – as they would have been during La conquista de Am�rica if they were to join the invasion. This was written for those German Jews who lamented that they were not accepted as true german nationalists… Same applies to nebach russian jews
