@rsviesh no, that actually sounds just in line with what Americans would do. you do realize that in the rest of the world they don't exactly have the best of reputations. USA is known for protecting war criminals, such as granting immunity to many Japanese war criminals post WWII.
hell literally every single one of your recent presidents would be considered war criminals if international law applied to them. The problem is USA has so much influence things like basic universal rights don't apply to them. literally.
Also it doesn't matter what the American soldiers think. They are soldiers and thus listen to command. It's clear that they seem reluctant to be there, however, their more likely corrupt officers have told them to do so and thus they fall in line.
