Let's not conflate it with non intervention. What Israel is doing is unconscionable. Everyone should be standing against Israel and condemning their actions. Had any other country acted this way they would be absolute pariahs excluded from international trade, had all their internationally held assets seized, and face reparations and limitations on their military.

Non intervention applies when there is a legitimate conflict and you don't take a side. Simply not participating in Israel's genocide is not what the vast majority of people want.
