Legitimacy of the 2003 Invasion of Iraq

A dispute exists over the legitimacy of the 2003 invasion of Iraq. The debate centers around the question whether the invasion was an unprovoked assault on an independent country that may have breached international law, or if the United Nations Security Council authorized the invasion whether the conditions set in place after the Gulf War allowed the resumption if Iraq did not uphold to the Security Council resolutions. Those arguing for its legitimacy often point to Congressional Joint Resolution 114 and UN Security Council resolutions, such as Resolution 1441 and Resolution 678. Those arguing against its legitimacy also cite some of the same sources, stating they do not actually permit war but instead lay out conditions that must be met before war can be declared. Furthermore, the Security Council may only authorise the use of force against an "aggressor" in the interests of preserving peace, whereas the 2003 invasion of Iraq was not provoked by any aggressive military action.
