Bin Laden comes out of a business background - he studied public administration and economics at university, and he worked for his family company, which was obviously a rather successful enterprise.

Bin Laden was 200 miles away from the area where all of these drone strikes were taking out his key leaders in al-Qaida. He was able to indulge in his hobbies... He was making occasional video tapes and audio tapes for release to the wider world.

So Pakistan is a country that I'm very fond of and have spent a lot of time, but it is a country where conspiracy theories have a life of their own.

At one point people in al Qaeda were actually drawing monthly paychecks when they were based in Sudan.

If you don't understand what al Qaeda was trying to do on 9/11, if you don't have a sense of who Osama bin Laden is as a person, if you don't have a sense of what al Qaeda, the organization, was on 9/11, 9/11 appears to be more or less inexplicable.

Bin Laden's death is just a punctuation point on a set of problems they've had for a long time. I think the prognosis for al-Qaida and groups like it is really bad, and that's a good thing.

There's some pretty good academic research that suggest that what Americans don't like is losing.
