It is important to add that even though the US has committed atrocities, for decades, from Vietnam, Cambodia, and Laos through Iraq, Afghanistan, and Gaza; illegal invasion, torture, genocide, war crimes; nothing meaningful ever came from it. There has never been Nuremberg trial equivalent for the United States, and there never will be. Every single president since Eisenhower, every single one, no exceptions, has been a war criminal by the standards of the Nuremberg trials and the Tokyo tribunal, and not one of them ever spent even a day in court for it.
There are no consequences for war crimes committed by Americans. None. Aside from 9/11, but the ones who died, the ones who suffered, were not the ones responsible for the atrocities committed by the US. So sure, "just following orders" isn't a valid defense, but you won't need one anyway.
