Just as one data point I happen to personally remember, the US blew up an MSF hospital in Afghanistan:

Not that that makes this ok, but it does put it in the category of "error", not deliberate targeting of civilians (if you believe that narrative, of course).
Not sure how well that aged now that the US essentially took all the money from the Afghan central bank.
Also, there have been leaked documents showing that the US would delibrately target ambulances and civilian infrastructure. I don't understand why anybody would take the US military's word as gospel without substantial evidence (and no, apologising and paying reparations after controversy is not compelling evidence that these actions were not delibrate).
Any time the military kills a terrorist, a certain group of people will say "You monster! He had kids for God sakes! Look at these pictures of his family! He never got a fair trial!" When a genuine fuckup happens, these same people naturally jump on the opportunity and criticize endlessly. The American population is especially apt for this kind of behavior.
The last problem the American people have is that they're too anti-war. It's literally the opposite.
