Gaza is the only place Israel is trying to take over with arms, and it's a red herring what happens to the people there.Sure, lets ignore everything going on in Palestine in the mean time, let Israel slaughter/displace everyone and turn it into fait accompli yeah? You would like that won't you, pity for you the world doesn't work like that
There's a community of at least a few million expatriated Palestinians. A bunch of them in the west Bank and a bunch keeping their heads low as Israeli Arabs.
The only thing that matters is if Israel government or the anti Israel resistance cracks first. And since the latter have essentially not taken signficant damage since the war started, escalation dominance remains with them. Even if Israel could kill 2 million Gazans Holocaust style, there would, just as it was with Jews after the Holocaust, remain more than enough Palestinians or other Arabs willing to suddenly larp as Palestinians, to settle and govern the Levant.
