Tolkien was, I believe, writing about his experience in the First and Second World Wars, where he would have spent a lot of time without any female contact. He was part of the fellowship of men who went to war, and I think, really, that's what he's writing about.

I think when I close my eyes what I think is 4,500 days or so, 4,250 I guess days, was long enough to give Iraq to come into compliance with the international order. And I think to myself how many Iraqi citizens died under the brutal regime of Saddam Hussein during those 4,200 odd days, and I think to myself how many more citizens of how many nations, the United States, Israel, or any other neighbor would die if Saddam Hussein went unchecked, though I am just grieved by the sacrifice of our brave men and women, but I think ultimately the greater good is served.

I did mega-training with ex-military men. I'd be in the gym for two hours after a 12-hour day on Spooks, and it was so hardcore I'd throw up. I stuffed myself with food and drank protein shakes to bulk up. I used to be a dancer, but I had to strap my weak ankles every day and strengthen my wrists so I could hold a machine gun. My body just wasn't up to it.

The development of weapons of mass destruction and the missiles to carry them would be a very destabilizing effect, should Iran be able to accomplish that.

What we said publicly is that we know that Saddam Hussein has chemical weapons, he's used them; we know about his biological weapons programs; and in the nuclear equation, left to his own devices, with no fissile material, by the end of the decade, he'll have a nuclear weapon. But if fissile material is provided to Saddam Hussein, he'll have a nuclear weapon within a year, so I'd say the year is the outside timetable.

I'd have described myself as a Tolkien reader before this, but now I'd describe myself as a Tolkien geek.

I'm the only honest person in Washington.
