Maybe a disclaimer ahead: it's absolutely atrocious what Israel is doing in Gaza. Leveling it and probably filling it with Jews when rebuilding it. The whole thing is a 911 like overreaction and I do not support any of it.

Does not matter what some court says it is or not. That piece of land will most likely be ethnically cleansed.

At the same time saying Israel has no right to exist can mean many things from not in it's current form to all Jews in the sea. That's the problem with dumbass slogans like this.
