A few years ago I read 'ISIS: Inside the Army of Terror' by Michael Weiss and Hassan Hassan, the story is so complex you'd need a road map. The Bush Cheney invasion of Iraq was the major factor in the creation of ISIS or ISIL or Daesh or ??? Republicans fail to acknowledge that as they have found most Americans are too busy and their dog whistle BS blaming Pres Obama works with their base.
"The book describes how ISIS emerged in the chaos of Iraq following the 2003 U.S. invasion, how the group was strengthened by the suppression of the Arab Spring and by the war in Syria, and how ISIS seized leadership of the jihadist movement from Al Qaeda."
