This is why Israel destroyed all Hospitals, Ambulances and Water supplies. In Gaza right now there is no water, no food, no hospital, no ambulances, they are driving tanks through buildings and killing everyone they see, and Israel wont be sweeping up after the big going away party they are throwing for the people of Gaza, that way they get to kill the rest off with typhus and cholera after they leave and it wont be part of their official death toll... it will be Hamas fault for "spending billions on rockets" rather than efficient medical services.
This is why the claim has been made that Hamas is "mass genociding" their own people. Because it paves the way for a wholesale slaughter - all of which can be blamed on Hamas. This is why Israel created Hamas. It is why Hamas rockets are fired at Israel in their hundreds and why they never hit anything or kill anyone. All has been orchestrated to provide the Israeli government the cover this rogue state required to cleanse Gaza of its people when it needed to.
