Here's a question for y'all to noodle over: why did Obama authorize the killing of Bin Laden now? I'd love to think that the US just learned of his whereabouts and the next minute authorized the destruction of the scum, but I'm afraid we've known for some time. Bin Laden was living in a freakin' villa in the middle of a large town, near military and government complexes. there was no way the Pakistani government didn't know. And ergo, the CIA must've known. So if we've been sitting on this info, why now? And it's not like we're shy of going in to Pakistan... we've been launching strikes and missiles openly for many months now.
A cynical part of me wants to say Obama wants to use the killing for political purposes ("Look at me! I'm a National Security Hawk!"), but this wouldn't be a good time to do it, politically. He should wait until closer to the election or when the polls say that he needs to be seen as a hawk. (Don't worry, though, Obama's gonna milk this for all it's worth, it's just that that politics did not instigate action.)
Obama is revamping his security leaders. I think that the new guys coming in have been charged with finishing Afghanistan before the 2012 election. They respond, "Fine, we can do it, but we need Pakistan's help. There's no way to win in Afghanistan if Pakistan doesn't close their huge border and allow the Taliban to play peekaboo with our military."
So Obama asked Pakistan, "Pretty please?", and Pakistan said, "F-U, Barak Hussein, we've got nukes." And Obama said, "Oh, yeah."
So a smart advisor (or Karl Rove) said to Obama, "Why don't we force Pakistan to help us? We can tell the world that they're protecting Bin Laden!".
Obama: "They'll never believe us. They'll deny it."
Rove: "Then we'll have to go in with some awesome Navy SEALs and kill the bastard and show him to the world. We'll then have an awesome card to play with Pakistan and they'll play ball."
Rove: "Yup, the same guys. But tougher."
