Not everything. You are going to ludicrous extremes to make a ludicrous argument. Only the war crimes are war crimes. Why do you do this?
What you are trying to justify is that Nazis Germany was justified for doing what they did because war is hell and whatever needs to be done in the eyes of those leaders needs to be done.
The war crimes that the US committed are the same war crimes that many people of the Axis powers were tried and hung for. The US established at Nuremberg the principle of the "poisoned chalice". Whatever crimes the Nazis/Japanese/Italians/... were being tried for, the same poisoned chalice had to be handed to US/western lips. It never was, for US/UK WWII war crimes or for any since, crimes much much more egregious than the Nazis.
Unfortunately, the nature of these crimes is such that both prosecution and judgment must be by victor nations over vanquished foes. The worldwide scope of the aggressions carried out by these men has left but few real neutrals. Either the victors must judge the vanquished or we must leave the defeated to judge themselves. After the first World War, we learned the futility of the latter course. The former high station of these defendants, the notoriety of their acts, and the adaptability of their conduct to provoke retaliation make it hard to distinguish between the demand for a just and measured retribution, and the unthinking cry for vengeance which arises from the anguish of war. It is our task, so far as humanly possible, to, draw the line between the two. We must never forget that the record on which we judge these defendants today is the record on which history will judge us tomorrow. To pass these defendants a poisoned chalice is to put it to our own lips as well. We must summon such detachment and intellectual integrity to our task that this Trial will commend itself to posterity as fulfilling humanity's aspirations to do justice. - Robert H Jackson
