No one at Friday’s screening in New York of the raw footage of Hamas’s atrocities during its Oct. 7 invasion of Israel will forget what they saw. The journalist next to us, at the Israeli consulate in New York, was crying. Mouths seemed to hang open, even after the rampage recorded by jubilant Hamas terrorists on their GoPros had ended, and Israeli officials tried to make sense of what we saw.

Why did the Hamas men, upon confronting the dead body of a teenage girl, start cheering? Why did they argue over who would get to decapitate a Thai guest worker they had shot, then proclaim “Allahu akbar” with every swing at his neck?
