From 60 Minutes Interview With Bob Woodward:
Mike Wallace: And Woodward says that no matter what's occurred in Iraq, Mr. Bush does not welcome any pessimistic assessments from his aides, because he is sure that his war has Iraq and America on the right path.
Bob Woodward: Late last year, he had key Republicans up to the White House to talk about the war, and said 'I Will Not Withdraw Even If Laura And Barney Are The Only Ones Supporting Me.' Barney is his dog."
