George W. Bush has only one regret about invading Iraq: that it paved the way for the Islamic State of Iraq and the Levant.

“I think it was the right decision [to go into Iraq],” Bush tells CBS News’ Bob Schieffer in excerpts of an interview that will air on Sunday. “My regret is that…a violent group of people have risen up again…This is ‘Al Qaeda plus’…they need to be defeated. And I hope we do…I hope the strategy works.”


Bush also told Schieffer that when he threatened to invade Iraq, Saddam Hussein did not take him seriously.

“You know, when he was captured — I was told that the FBI agent that talked to him, he said ‘I just didn’t believe Bush,” he said. “And it’s hard for me to believe he didn’t believe me.”

Bush added, “In retrospect…I don’t see how he could doubt my word.”

Bush is currently promoting “41: A Portrait of My Father,” a biography written by Bush about his father. The biography is set to be released on Nov. 11.

The two-part interview will air on CBS News’ “Sunday Morning” at 9 a.m. on Sunday, Nov. 9, and will air again during “Face the Nation” at 10:30 a.m. during the show’s 60th anniversary special.
