A quote from US Supreme Court Justice and Head of the Nuremburg Tribunal Robert Jackson:
"We must make it clear to the Germans that the wrongs for which their fallen leaders are on trial is not that they lost the war but that they started it. And we must not allow ourselves to be drawn into a trial of the causes of the war, for our position is that no grievances or policies will justify resort to aggressive war-- it is utterly renounced and condemned as an instrument of policy."
