I think the world is more perilous and America is basically undefended. For me the two touchstones after 9/11 for domestic security were our borders. Not for discriminatory reasons or to stop immigration, but simply to allow law enforcement to find out who is in our country without facing an undocumented pool of aliens that increases by the hour.

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.

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.

In an odd way, we have really destroyed two of our strongest allies against the Islamists. Saddam Hussein, and we've probably fatally undermined Bashir al Assad in Syria.

If the Americans attack Iran for the first time in 1,400 years, we may unite Sunnis and Shias against us. So I guess there is room for accomplishment everywhere.

And when you say the policies are what caused this war - American policies - that's not to say that they're wrong. It's not to say that the policies were made by madmen or evil people. It's simply to say that you better understand the motivation of your enemy if you're going to defeat him. And the man who is motivated by a belief that his religion is being attacked by a superpower is much more dangerous than a man who's mad at you because you have women in the workplace.

What I tried to do is to present the evidence that's available and that no one has been able to refute. Not even the Arab governments who own their media have been able to denigrate bin Laden as a man.
