We sure won’t somehow have less problems by leaving Iraq in a huge mess! And we won’t have less problems by simply miding our own business. It’s not that simple.
It would be wonderful if EVERYONE subscribed to that notion though...then by golly, I’d be right with you on that!
What makes you think we can fix the problems in the ME if they haven't been able to fix them themselves for oh I don't know, hundreds of years?
