Incredible how readily people like this will accept open holocaust denial. Bandera and the OUN weren't quiet about their politics, their participation in pogroms, or their collaboration with Nazi Germany. We don't need to speculate about their motives, they came out and said them quite freely:

"We are raising a militia that will assist in the extermination of Jews... I am of the opinion that the Jews should be annihilated by applying the German methods of extermination in Ukraine."

"When it comes to the Polish question, this is not a military but a minority question. We will solve it as Hitler solved the Jewish question."

"...wipe out Poles, Jews, professors, officers, leaders, and all established enemy elements of Ukraine and Germany."
