Instrument

"We must make clear to the Germans that the wrong for which their fallen leaders are on trial is not that they lost the war, but that they started it...No grievances or policies will justify resort to aggressive war. It is utterly renounced and condemned as an instrument of policy."
--Justice Robert H. Jackson (1892-1954),
U. S. Supreme Court Justice
