war of aggression

A definition of war contrasted with just war.

"To initiate a war of aggression," said the judges in the Nuremberg trials of the Nazi leadership, "is not only an international crime; it is the supreme international crime differing only from other war crimes in that it contains within itself the accumulated evil of the whole." In stating this guiding principle of international law, the judges specifically rejected German arguments of the 'necessity' for pre-emptive attacks against other countries. Including for instance against Iraq.
