Ample records of disproportionate strikes? Yes. Ample records of targetting civilians? No. Those rules of engagement are absolutely followed, and we know this from the thousands of instances where strikes were called off because civilian presence in the area changed. They keep endless records because they are accountable to Congress.
It's a moot point when comparing America to ISIS because terrorists definitionally don't have any concept of proportionality because killing civilians is the goal.
I don't really care to argue I/P, that conflict is forever fucked and nobody knows anything about it.
