I truly believe that if torture had worked and there was a case to be made for it, we would see that on the front pages of the American press.

My take on the torture thing and even drones is: If we're going to get into assassination and torture, the second question is the morality, but the first is the effectiveness of it.

There is a tendency in any conflict, especially in a democracy, to fight the enemy you can, not the enemy you should.

The US have dealt with Iran. I'm not saying attack it; I'm saying we should have taken it seriously. The Iranian connection to 9/11 is much stronger than the Iraqi one ever was. That was the big lie: That Saddam had something to do with 9/11 - not the WMD - the connection between Saddam and bin Laden. We were spun on that and we were spun on the famous Prague meeting between Mohammed Atta and Iraqi intelligence, which was a complete lie. Both the CIA and the FBI came out and said that never happened.

Destroying Iraq was the greatest strategic blunder this country has made in its history. Unless we change course, there's every reason to believe the Iraq War will end up changing the United States more than it will ever change Iraq.

Did bin Laden act alone, through his own al-Qaida network, in launching the attacks? About that I'm far more certain and emphatic: no.

If you want prisoners to be tortured, you send them to Syria. If you want someone to disappear – never to see them again – you send them to Egypt.
