Even if the world believed the ridiculous claims of the IDF that Hamas bases were everywhere and these claims without proof justified bombings that are war crimes in the absence of proof that the facilities were being used militarily….the fact remains that Israel can never show that waiting a day or so until the alleged Hamas personnel exit from the hospital is going to make it impossible to kill their supposedly real Hamas target without the civilian deaths.
Israel can stage as many propaganda videos they like of alleged Hamas HQ rooms, but these animations and fictional interpretations of non-evidence are never going to be a successful war crimes defense when all Israel had to do was wait a while and attack the supposed target after they exited the building.
