Obama seems unduly defensive, first making clear he really didn’t commit himself in March:

That’s why, shortly after taking office, I approved a long-standing request for more troops. After consultations with our allies, I then announced a strategy recognizing the fundamental connection between our war effort in Afghanistan, and the extremist safe-havens in Pakistan. I set a goal that was narrowly defined as disrupting, dismantling, and defeating al Qaeda and its extremist allies, and pledged to better coordinate our military and civilian effort. 

And he denies he has deprived our forces of help by his prolonged decision-making:

Let me be clear: there has never been an option before me that called for troop deployments before 2010, so there has been no delay or denial of resources necessary for the conduct of the war.

Instead, the review has allowed me ask the hard questions, and to explore all of the different options along with my national security team, our military and civilian leadership in Afghanistan, and with our key partners. Given the stakes involved, I owed the American people – and our troops – no less.

And then he feels compelled to tell us he opposed the Iraq war. Then he feels it necessary to tell us how hard the decision it has been. I fail to see why any of this is helpful to him in rallying public opinion or impressing our adversaries.
