http://www.globalpolicy.org/security/issues/iraq/attack/lawindex.htm>This sections examines the legality of the 2003 US-UK war on Iraq. Shortly before the outbreak of hostilities, UN Secretary General stated that the use of force without Council endorsement would "not be in conformity with the Charter" and many legal experts now describe the US-UK attack as an act of aggression, violating international law. Experts also point to illegalities in the US conduct of the war and violations of the Geneva Conventions by the US-UK of their responsibilities as an occupying power. The section also looks at wartime violations on the Iraqi side.
