Iraq’s chemical, biological, and nuclear weapons programs, together with Iraqi long-range missile development and support for al-Queda terrorism, were the primary justifications put forward for military action. On March 17, 2003, President Bush issued an ultimatum demanding that Saddam Hussein and his sons depart from Iraq within 48 hours. On March 19, offensive operations began with air strikes against Iraqi leadership positions. By April 15, after 27 days of operations, coalition forces were in relative control of all major Iraqi cities and Iraqi political and military leadership had disintegrated. On May 1, 2003, President Bush declared an end to major combat operations. There was no use of chemical or biological (CB)weapons, and no CB or nuclear weapons stockpiles or production facilities have been found.

Iraq’s Kurdish community, repressed by previous Iraqi governments, has become a major force in post-Saddam Iraq. The Kurdish-inhabited regions of northern Iraq are relatively peaceful, reconstruction is proceeding there, and the Kurdish leaders now have senior positions in the post-election government. However, there are concerns that the Kurds might use their political strength to serve their own interests at the expense of a unified Iraq. This report may be updated.
