In order for Israel to defend themselves, they would have to turn Gaza into a tent camp. No electricity or water. They’ll have to remove every structure from Gaza.
The way I’ve seen those buildings collapse in Gaza, all it takes is 1 bomb and down it comes. Twits going to take a lot of bombs for the number of buildings I’ve seen.
They don’t have to actually occupy Gaza. Leveling it may be plenty for the purpose. I’m not sure that’s equivalent of “ethnic cleansing.”
