Leading. It's what leaders do. No surprise, most people don't recognize it because most adult Americans have never experienced serious presidential leadership. Last time it happened, sadly, was during the Reagan years. (Also sadly . . . .) (No. I was not a fan.)
President Obama is moving quickly (or trying to do so) and tackling short-term problems: He's facing the enemy at the gates. But he's also engaging in the second, and perhaps more important task, of a good leader: Trying to figure out how and why the enemy got there in the first place, and thus trying to prevent it from happening again.
Put another way, he's tackling the immediate issues, while taking the long view of the big picture. He's leading.
