your last thought is a scary one. During the holocaust the same thing happened in the USA. Not only that but its reported by Gisee Flieshman HYD from R weissmendl ZL group that she went to collect money and warn the jews of Hungary, just across the Slovakian border. They were partying and laughing at her living in the most lavish mansions and wearing fancy furs. The only limud zechus I’d say is, during the holocuast, it was a constant continous expansion of murdering more and more jews every day. It wasn’t just about an existimng group of jews. It was also very large in scale. Of course even on jew is too large. But if you take the mass destruction that occured continuously daily during the holocuast its very differet than this war.
Another way to say this is, I think we all know someone who is suffering endlessly with yena machala in the hospital. I remember when my moth a’h was terminally ill with it and in enormous pain in the hospital. I skipped every simcha and was appalled by how people can just dance and live normal loves while my mother is almost in the olim haemes and yelling in pain. Now we should feel like this about every jew. But is that what hashem wants? Whats the balance? I’d say definitely if it were a holocaust then no but when yes???
