Following the invasion, the U.S.-led Iraq Survey Group concluded that Iraq had ended its nuclear, chemical, and biological programs in 1991 and had no active programs at the time of the invasion but that Iraq intended to resume production once sanctions were lifted. Although some degraded remnants of misplaced or abandoned chemical weapons from before 1991 were found, they were not the weapons which had been the main argument to justify the invasion. Some U.S. officials also accused Iraqi President Saddam Hussein of harboring and supporting al-Qaeda, but no evidence of a meaningful connection was ever found. Other reasons for the invasion included Iraq's financial support for the families of Palestinian suicide bombers, Iraqi government human rights abuse, and an effort to spread democracy to the country.
