Newsflash:  Iraq had NOTHING to do with 9/11.  Like those WMDs, the "intelligence" that Saddam was dirextly involved in supporting the 9/11 terrorists was absolutely false.  This has been validated over and over.  Let's not forget both happened during the Bush administration.  I think Obama's great failure will be his inability to somehow successfully extricate us from the morass of the Middle East.  If Trump can manage that, I will be the very first to give him credit.  regards, Gary Crum
