>Israel's response to Hamas' attack nearly two years ago now is likely even stronger than the USA's to 9/11

I dunno about that. Iraq suffered between a quarter million and a million dead (depending on how you count). The % of those who touched a gun is low, under %10. The vast majority are civilians.

There wasn't a focused effort to bring in food, water or electricity to Iraq. A key difference is that Iraqis could leave, and hundreds of thousands did (to Syria, Jordan and other countries).

Israel's war in Gaza, messy and horrible as it is, is far (very far) more focused on Hamas than America's wars were in Iraq and Afghanistan.

I should have phrased it differently, I meant the psychological response, not the military response.
