I like the term "extermination" which the ICC's chief prosecutor used in his charging document against Bibi.

Genocide requires intent. There is at least the possibility that Israel is merely showing careless disregard and willful ignorance towards Palestinian lifes. That doesn't make a practical difference, of course. The fact that Israel is maybe? not as racist as they could be, doesn't help all the dead or starving civilians.

That's why I like the term extermination. It's precise but doesn't require intent. It doesn't imply that Israels interest in defeating Hamas is merely a smokescreen (for the record: I don't think Hamas can be defeated militarily, but I understand the interest).

And it does all that without being a euphemism.

Edit: a previous version of this contained a Freudian slip where I confused the names of Biden and Netanjau.

Ethnic cleansing is the part where they displace the target population.

Genocide is the part where they kill the target population.

Obviously there's a fair bit of overlap between the two.

Definately war crimes.
