I’m afraid most of the lessons of Nuremberg have passed, unfortunately. The world has accepted them, but the U.S. seems reluctant to do so. The principal lesson we learned from Nuremberg is that a war of aggression — that means, a war in violation of international law, in violation of the UN charter, and not in self-defense — is the supreme international crime, because all the other crimes happen in war.
Nuremberg prosecutor Benjamin Ferencz as quoted by Glenn Greenwald.
This point was similarly brought up by Telford Taylor, another Nuremberg prosecutor (in fact, one of the chief prosecutors for the United States), in regards to the Vietnam War. Taylor more so pointed out how the bombings of villages suspected of harboring enemies in North Vietnam, Cambodia, and Laos were "flagrant violations of the Geneva Convention on Civilian Protection". I suspect he would find President Obama in similar contempt (to say nothing of the disgusting practices of the Israeli armed forces).
And again, what makes the “War on Terror” particularly disgusting and unjust (and, if we are to learn anything from Nuremberg, prosecutable) is that it twists the head off of the idea that war (and especially war of aggression) is in itself one of the most heinous crimes as it inevitably causes a cavalcade of subsequent and related injustices.
