I see nothing immoral about this scenario and it slides the reader down a slippery slope towards the ICC/Hague, where both entities would without hesitation trump the US Consitution with vigor IMO. The world is not one village where enlightened men have created a gold standard of morals and law to be enforced by fallible men. First, the species must necessarily kill one another from time to time and that is a hard nut for some to crack despite the evidence of recorded history and the literal sea of blood that has been shed over the centuries. Secondly, the apalling impotency of powerful nation states to directly intervene during times of real genocide, i.e. Rwanda, Darfur, Cambodia, Columbia, the Congo, etc leaves this scenario essentially a parlor game where but a privliged few get to participate and fallible men of action are forced to stand idle. Said nation states are packed to the hilt with Law and Morality.
