The main thing is that Isreal intentionally blocked and prevented critical aid from reaching a starving population of civilians. Thats the core of the genocide case because it demonstrates motive and intentionality to hurt only the civilian population. The report that revealed this was what flipped my opinion from supporting isreals response and war objectives.

People call bombing buildings and killing civilians genocide but its an expected part of this type of war. If the enemy hides among the civilian population you can kill the civilian population. If the enemy hides in buildings and booby traps them, you can destroy the buildings.
