Israeli impunity has allowed them to commit an ever escalating series of atrocities and crimes against humanity without any consequences.
They ratchet up the crisis meter by slaughtering Gazans and picking fights with Lebanon and Iran. They spend millions of American taxpayer dollars on killing thousands of civilians in indiscriminate attacks (see the Dahiya doctrine). And the US has shielded them from any accountability at the UN.
The net result is that there was no true opportunity for nonviolent and peaceful de-escalation. None of Israel's allies want Israel to stop, because their own imperial interests rely on the "total victory" of the revisionist Zionists.
The only real route to stopping the collective mania of the Israeli government was through inevitable retaliation by a regional hegemon.
