The much much more likely situation is that a third of gazans leave based on plans that western governments have made for gaza that are already public.
Thats the outcome that those groups are currently on a clear trajectory towards, that might not even be stoppable at this point, TBH.
Then what? More yelling online about "zionists" doesn't rebuild the mass rubble that gaza has already been turned into.
But hey, feel free to check up on gaza in a year and see if things have gotten any better, or if it has instead just been more people sacrificing their lives for nothing with no progress towards a better future.
