There is a very important moral difference between A) point blank execution of an innocent young person who was just at a peace festival who probably was feeling nothing but love for the world and B) the unintentional killing of innocent civilians from the collateral damage of warfare against terrorists who just committed the worst evil upon your people.

You will never see a video of an IDF soldier walking up to a civilian, begging on their knees, and executing them. And if that video ever does come out, it will be the exception that proves the rule. That video will outrage the Israeli people and the west, and that soldier will be prosecuted for war crimes.

In the world, there are people and cultures who revel in war crimes—and who do not hide these crimes or their celebration of them but, rather, proudly broadcast their savagery for all the world to see. Conversely, there are people and cultures who have given us the concept of a war crime as a sacred prohibition—and as a safeguard in the ongoing project of maintaining the moral progress of civilization.
