ahh yes. Because the Israeli army has literally no options between “relentless bombing of Gaza, denying access to food, water and medicine, sniping civillians trying to flee according to your demand on the safe routes you designated and bombing ambulances trying to move patients in the same way” and “doing nothing and watch Hamas regroup.”
Israel could have led an infantry assault into Gaza withou pounding everything first. That would have meant higher casualties though and here shows the true nature of Israels government and army.
They do not care for any palestinian life. So far for every Israeli soldier that got killed, more than 200 palestinian civillians were killed.
In world war 2 the axis powers killed about 6 civillians for every axis soldier and the allies killed about 1 civillian for every 4 ally soldiers. So the war that was about total destruction and genocide still had more than a magnitude less civillians killed relative to combatants killed.
