I was more opposed to the Iraq war than 99.9% of Americans, and this is just ahistorical bullshit.

You can go look at Basra right here:

Over a million people live here. The estimate was that "448 to 593 civilians were killed due to coalition military operations", orders of magnitude less than Israel has killed. Basra was not wiped off the map or seized and annexed by coalition forces while the population was herded into a concentration camp.

It is simply slander against the US military to suggest they have in the 21st century done anything like what the IDF has done in this genocide.
