[But the Russian nukes in Kaliningrad are widely accepted and not controversial, right?]
Russia is possibly one of the few powers in WWII that emerged at the end of the war with significantly more territory than it had at the beginning. For a country that kicked the war off by allying with Germany to annex Poland, thereby giving Germany a free hand in the West, its image is remarkably good. I credit Russian propaganda efforts combined with those of fellow travelers in the West.
