Fascism doesn't have to make sense, it's pure affectation.

Eastern European fascists were kept down by the communist governments which is perfect fuel for their martyr fantasies. And the communists were not real Poles/Latvians/etc., they were evil foreign Russians (and/or Jews) so that's why they hate Russia.

They love America for supporting them back when they were being "persecuted", for supporting them now and for being Russia's main enemy.
