The question people need to be asking isn't whether there's any hope for the Palestinians left? There isn't. There never was and never will be any hope for them until they're exterminated. And this act will be sanctioned by any US administration and most other Western democracies as well. Humanity will all collectively turn a blind eye while they are crushed out of existence.This just feels like a lost cause. All the western countries will fall over themselves to support Israel and the Arabic countries don't care enough to do anything, so this will happen until there is no Palestinia left.
The question that needs to be asked is what will Israel choose to do with its influence once they're gone? Because that's not something you just up and discard after achieving your initial aims. You instead see what else you're able to do with it.
