not to detract from your point, but that is quite literally what happened, and the resemblance is fucking terrifying.
around the time when the 1943 warsaw ghetto uprising began, the nazis set up a merry-go-round right next to the ghetto's walls along with music, and people were dancing, having fun in the pleasant april weather. marek edelman, one of the most prominent leaders of the uprising and a notorious anti-zionist as well as a leftist organizer, in the book "shielding the flame" (which i believe everyone should read as it provides insight into how the ghetto operated and made me realize how uncannily close the sitation looks like modern day gaza), stated that he could hear the music outside, and he could see the happy people, and he was so, so terrified that all that joy outside will drown out their screams for help, the gunshots and the fire.
