I would agree with you if Israel had not bombed areas it deemed ‘Safe Zones’ several times killing twice and thrice displaced Palestinians who are shocked, starving, dehydrated, and incapable of getting medical treatment or even fuel for their car to leave.
The argument of the safe zones or Gaza city all falls apart once you read the facts.
You seem like a smart person. How do you feel about the IDF bombing areas they told people to move to? And how do you feel about the IDF forcing people to evacuate areas in which the refugee camps are already full, meaning there would never be enough space or food for them?
