If Germany or Japan is your guideline here, maybe Israel should get a Bomber Harris (https://en.wikipedia.org/wiki/Arthur_Harris#Second_World_War) or a Truman (see nuclear weapons dropped on Japan) on the scene?

People are saying that what Israel is doing right now is a genocide. You have seen nothing yet: With either of them at the helm, there would either be an unconditional surrender by Hamas or no Palestinian alive anymore - and by November 15, last year.

We don't do such things anymore, and for good reason, but that means that these past situations are unsuitable as example for the present.
