Not it has been said! rather it is known that many Ukrainians, governments, etc were not just sympathisers, but active and willing participants in the genocide and exterminations of ww2. 

Owing to post war communist control much of the archival material and atrocities commited against jews and other minorities during ww2 and post war soviet control is only slowly coming to light! 

This in spite of the Holodomor genocide commited by the soviets against Ukrainians starting in the 1930s
