Comment about GWB failing has to do with perception, not anything he believed or said. Only that he/they didn't stop popular opinion from desiring or expecting a one or two year flip.
He has not wavered in his doctrine. If he has not been heard, it is not because he hasn't been speaking, but because 1) we aren't paying attention. 2) one man (no matter how big the bully pulpit) can't drown out the media.
I lurked a long time before I started posting. I read countless threads about the President's inability to speak. I disagree most heartily with this assessment. He has done a very good job in laying out his objectives and the length of time it will take us to win. He has told the Americans why they must stay and fight and win in Iraq.
Now, I know that I am in the minority with this view. But, to me, he has been very vocal and articulate. His views (except for his policy towards the Palestinians) are why I support him.
