What are crimes against peace?
Crimes against peace, also known as crimes of aggression, were described by the Nuremberg Tribunal as “the supreme international crime differing only from other war crimes in that it contains within itself the accumulated evil of the whole”. The Nuremberg Principles define them as follows:
The crimes hereinafter set out are punishable as crimes under international law:
(a) Crimes against peace:
(i) Planning, preparation, initiation or waging of a war of aggression or a war in violation of international treaties, agreements or assurances;
(ii) Participation in a common plan or conspiracy for the accomplishment of any of the acts mentioned under (i).”
