Hitting critical civilian infrastructure like schools, hospitals and desalination plants are all war crimes. As are double tap strikes where you bomb the same place later to kill aid workers. I imagine Israel asked the US to join in Israels ongoing campaign of war crimes so they dont have to be alone in that. When the US whitewashes its crimes in a few years I suppose Israel will hope to blame the US for all of their years of war crimninaity and sleeze their way out of their own accountability.
