So it's ok for Germans to worship Hitler because he was a nationalist? Do you know what Bandera and his crew did to Poles during the war?
Bandera was in a nazi concentration camp at the time.
Bandera personally did nothing to the Poles, he was in a German jail most of that time. However, Ukrainian nationalism of course would be opposed to Polish domination of Ukraine just as much as it would be opposed to a Soviet domination of it. That UPA committed war crimes I have no doubt; so did the Soviets and the Germans. It was a brutal war.
