If he is alive… does it really matter? I mean, I want him dead, but in terms of al-Qaeda, ObL is effectively dead. He can’t give orders, or even communicate — except in a low-level, messenger-service way, with notes or a smuggled tape. He’s no longer nearly as much of a popular figure. And eventually he will die, if he doesn’t get medical attention.
We need to remember that this isn’t a war against Osama; it’s a war against terrorism generally and al-Qaeda specifically. Osama without al-Qaeda is just one sick man, but al-Qaeda without Osama is still dangerous. If the choice is between continuing to hunt Osama or going after al-Qaeda affiliates in Africa or Southeast Asia, we need to choose the latter.
