I think once again you are simplifying events to form a narrative. Urman is a small village on the western border with Poland. Its history has it changing hands several times most recently being created as an entity after being part of the Austrian-Hungary Empire. It lies very close to the Polish/Ukrainian border and after the invasion of Poland by both Germany and the USSR it was part of the Russian/USSR territory.
In other words it is totally meaningless as to whether Urman was Polish or Ukrainian. It had been subjugated by Russia and many people in Europe hated the communists of the day and wanted to be liberated from them.
Germany was the only game in town to join at that time if you wanted the USSR out and to join the German military as a foreigner - either Pole or Ukrainian or otherwise - had to join the Waffen SS.
The Waffen SS was distinct from the SS even though ultimately under the same commander. In the broadest and general terms - the majority of the SS were involved in war crimes but not general combat operations. The majority of the Waffen SS and the Wehrmacht were involved in general combat albeit some were from time to time involved in war crimes.
One additional factor to take into consideration is that Germany had no monopoly on antisemitism. It was wide spread at the time particularly in Eastern European countries including Poland, Hungary, Russia and many more. That's not to excuse Germans - they developed the art on an industrial scale - but to make it clear that there wasn't any given national or regional boundary with good guys on one side and bad guys on the other. There is no allegation that I have seen that Hunka was ever involved in a war crime.
What is one hundred percent clear is that the speaker made a gross and fundamental mistake which embarrassed not only this country but Zelenskyy as well. As
@Baloo stated above: if you fought against the Russians in WW2, you would in all probability have been in the Waffen SS which in western eyes is associated with the SS. That should have been a red flag to anyone with the most basic understanding of history. Anyone who screws up at this level should no longer hold a job of any importance.
