Lets be clear Hamas supporters are calling for a ceasefire so that they can resupply. There was a long ceasefire in place up until 7th October, when they committed an act of war on their neighbour. I am sure the Hamas leadership are not stupid. Why would they commit such a terrible act of war against a military superior opponent? It's clear they wanted to start a war in the Middle East and draw others in to help them destroy Isreal.
It hasn't worked. So arguably now, they fight asymmetrically and maximise the loss of civilian life to cry brutality. if they really cared about loss of civilian life they could negotiate a surrender or even the release of hostages in exchange for the creation of a safe zone.
