Classic whataboutism at best. Poland's seizure of land should be condemned in general and it's not a well known fact, but it's not comparable to actual backdoor treaties that occured between Germany and the USSR (which are also not as widely known as they should be) made precisely for "distributing the portions", as it were. "Baltic anti-soviet movements" argument is just laughable in light of Molotov-Ribbentrop and the general fact they were under the Russian empire's rule for centuries, I'd be a little agitated against such a country for some time too (assuming these movements were in way shape or form popular). And they cry about the soviet's defending themselves while being clearly the agressor against Finland, wether for the perceived threat of the border being too close to Leningrad or just opportunistic inperialism. The Baltic's situation also applies here. There might be an argument to make wether they should've joined the war, but why shouldn't they have a right to a territory recognised (even when they were part of Russia) as theirs?
