I don't know what our capabilities are. If I were there, I think it would be nutty to do that. The only country on Earth more containable than Iran is Iraq. And we've certainly made a mistake there. We could have continued Saddam.

So what we have is an American foreign policy that is inextricably linked to domestic matters. It is very dangerous for a politician who desires nothing more than to stay in office to address the mindset that any change in policy is appeasement. And Americans will accept that for a certain amount of time.

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.

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.

The Islamists started this war. They explained to us as clearly as General Giap and Ho Chi Minh explained to us why they were fighting us, and we have ignored it. Mrs. Clinton has ignored it, Bill Clinton, George Bush, Barack Obama. The idea that they're attacking us because of our culture is insane. We are now waging a war against them culturally. We're trying to impose democracy, women's rights, parliamentary systems on a people who don't want it. They're going to fight that.

The FBI continues to be a broken, anachronistic organization, but state and local law enforcement officials are much more attuned to the kind of threat we're facing. I think that's very hopeful, but it's a long-term process.

You just have to come to grips with the fact that people don't like to be invaded or bombed by anybody. And America has been engaged in that.
