He could, but he won't. Because it is so much easier just to make a speech.
He won't because it would mean he was wrong. Obama will never admit to being WRONG about anything. He will admit his administration has made mistakes, but he will never admit to personally being wrong. He is a true narcicist. Heck, he couldn't even give Romney credit for being right about Russia, because someone might insinuate that Obama was therefore wrong.
