It should be pretty clear when I say loaded terminology.
genocidal
This is not an accusation to throw around lightly. If it was, we could say that Palestinians were once genocidal, for instance, while they were targeting Jews with violent campaigns. As terrible as it is, urban combat is going to produce unintended casualties. It’s an extremely complicated, tangled mess to uncover genocidal intent amid an active war.
colonial
The Ottoman Empire (yeah, this was so long ago that those were still around) collapsed, the British Protectorate sanctioned the country of Israel, land titles were sold to the JNF, the Palestinians besieged Jerusalem in a bid to starve all of its Jewish inhabitants to death, and Plan Dalet was spawned to rid neighboring villages of potential combatants during an active war with a stated goal of allowing anyone non-hostile to remain. Doesn’t sound very colonial to me, especially given that there was Jewish owned territory in the region, long established before this conflict, and there were no other Jewish countries.
ethnostate
Israel allowed Palestinian refugees to return. The surrounding Arab nations didn’t and don’t. What else is there to say?
