No one should be surprised when Osama bin Laden and al Qaeda detonate a weapon of mass destruction in the United States. I don't believe in inevitability. But I think it's pretty close to being inevitable.

You can forgive your leaders for not knowing the intricacies of Islamic history. You cannot forgive them for not knowing their own. And when you look at American democracy, where did it start? It started, if you need to pick a point, at Runnymede in 1215. We have now been at this process, we and our English-speaking allies, for 800 years.

I think Mr. Clarke had a tendency to interfere too much with the activities of the CIA, and our leadership at the senior level let him interfere too much. So criticism from him I kind of wear as a badge of honor.

The war in Iraq - if Osama was a Christian - it's the Christmas present he never would have expected.

He [Osama bin Laden] is clearly an odd combination of a 12th-century theologian and a 21st-century CEO. He runs an absolutely unique organization in the Islamic world. It's multiethnic, multilinguistic, multinational. He is a combat veteran, three times wounded. He has a huge reputation in the Islamic world for generosity and leadership. He's a man who speaks eloquent, almost poetic Arabic, according to Bernard Lewis.

The second touchstone for America I think unquestionably was pushing to conclusion the program we had with the Russians to control the Soviet nuclear arsenal. I tend to think that more than anything else, that will come back to haunt us.

There is a direct correlation between what al Qaeda says and what it does. And the one thing that has been the gold standard of correlation has been bin Laden's 1995 - or was it 1996? - pledge that every attack is going to be more powerful than the last. If you go back to the first attack in Yemen in 1992 and chart it out, every attack has been more powerful, more destructive than the last one.
