There's simply no comparison between the Afghanistan occupation and what Israel is doing in its occupied territories.

Stupid and ultimately futile though the former mission was, the allied countries never thought they had a historical claim (or even any specific interest) in Afghanistan the way Israel covets (and certain factions within it openly proclaim their intent to fully displace the native population from) the West Bank and Gaza.

We save that rhetoric [accusations of genocide] only for Israel.

Plainly false, given the plethora of genocide rampages in recent decades.

And the extremely prominent media coverage of these situations, which cannot possibly have escaped your notice.
