History: Old Iraq

However, according to a comprehensive U.S. government report, no weapons of mass destruction have been found. There are accounts of Polish troops obtaining antiquated warheads, dating from the 1980s, two of which contained trace amounts of the nerve gas cyclosarin, but U.S. military tests found that the rounds were so deteriorated that they would "have limited to no impact if used by insurgents against coalition forces. The possible effect upon civilians was not discussed."
• Occupation
Following the invasion, the United States established the Coalition Provisional Authority to govern Iraq. Government authority was transferred to an Iraqi Interim Government in June 2004, and a permanent government was elected in October 2005.
After the invasion, al-Qaeda took advantage of the national resistance to entrench itself in the country. On December 30, 2006, Saddam Hussein was hanged. Hussein's half-brother and former intelligence chief Barzan Hassan and former chief judge of the Revolutionary Court Awad Hamed al-Bandar were likewise executed on January 15, 2007; as was Taha Yassin Ramadan, Saddam's former deputy and former vice-president (originally sentenced to life in prison but later to death by hanging), on March 20, 2007. Ramadan was the fourth and last man in the al-Dujail trial to die by hanging for crimes against humanity.
