Poland? Czechoslovakia?
What the fuck is going on here at HN? Is this Bizarro World?
Not that facts matter to you, but Poland attacked Soviets in 1920. Slovakia (Tiso regime) joined Hitler's forces on eastern front. They also attacked Poland and had a war with Hungary, both in 1939.
But given your attitude I'm pretty sure there won't be any meaningful discussion so I'll leave it at that.
the 1920 war was a result of that, Poles trying to reclaim territories in Ukraine - using the chaos of the Russian Revolution. but yeah, totally attacking Russia.
but all of that justifies the occupation by the Red Army from 1945 till 1989. yup.
