Israel would have acted like the genocidal white supremacist settler-colonialism state it has been since it’s creation.

Israel has never been genocidal, for obvious reasons. If wiping out Palestinians were their goal, they certainly could do it more effectively, IDF is often warning people about incoming attacks, and publishing justifications for attacks.

The reason Palestine lost land was because they declared war on Israel and lost, refused to concede, declared war again, lost, refused to concede, then continued terrorist attacks against them for the next 60 years.

But sure just call it colonialism or genocide or whatever fucking buzzwords you think will get public opinion to give a shit about this group that absolutely caused their misery by remaining uncompromising, violent, and poking the bear every chance they get.

Regarding the whiteness of Jews:

Significant percentages of Israelis are very non-white, but I know you're just doing mental backflips trying to inappropriately conflate Israel with their old enemies, the Nazis.
