Since the troop surge in Iraq is having success, he couldn't very well take the troops from Iraq and move them to A'stan. So, he had to bring additional troops into A'stan.
To the end he never quite could bring himself to acknowledge that he had misjudged on how effective the surge in Iraq would be. He almost seemed to imply that the results were not "real".
While I don't disagree that this is a needed action (McCain advocated it in the debates as well), it is more distressing to see that O seems to be getting on-the-job training; that he had little grasp how the view would be once he was at the helm. My sense is that his campaign words were either uninformed or purposely misleading ... either of which earn my trust in his competency and/or honesty.
