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.

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.

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.

And we're being attacked because of what we do, not because of who we are. And by refusing to talk about that, I'm afraid the American people, at least, don't have a good idea of just how dangerous the threat is that we face.

I also think that there is a huge failure in the American education system to educate Americans about where we, our system, our government, came from. And to some extent this failure is shared in places like Britain and Canada and Australia.

Well, there are certain pockets of improvement. The one that I think is most important is that state and local law enforcement levels have started to do a lot more educative efforts within their organizations to understand the kind of threat we're facing. They've given up on the federal level.

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.
