It used to be you needed to have a very large sophisticated state before you could even have a nuclear weapon... Now the technology is widespread enough. It doesn't take very many people to be able to cobble together a devastating attack, and all it takes is one.

I'm one of those people who believes that part of the greatness of the United States is our private sector. It's what we do as private citizens for ourselves and our companies. And our economy is essentially the wonder of the world because, in fact, it's produced so much for us over the years.

Saddam Hussein had a lengthy history of reckless and sudden aggression. He cultivated ties to terror -- hosting the Abu Nidal organization, supporting terrorists, and making payments to the families of suicide bombers. He also had an established relationship with Al Qaida -- providing training to Al Qaida members in areas of poisons, gases and conventional bombs. He built, possessed, and used weapons of mass destruction.

I'm often asked why I left politics and went to Halliburton and I explain that I reached the point where I was mean-spirited, short-tempered and intolerant of those who disagreed with me and they said 'Hell, you'd make a great CEO', so I went to Texas and joined the private sector.

The question in my mind is how many additional American casualties is Saddam worth? And the answer is not very damned many.

Like many Americans, I've always been intrigued by Bill Clinton. I obviously didn't always agree with him - enjoyed running against his legacy in 2000, when Al Gore was his designated successor, but I don't have anything negative I would say about Bill Clinton.

The threat is there. It's very real and it's continuing. And what the Obama people are doing, in effect, is saying, well, we don't need those tough policies that we had. That says either they didn't work, which we know is not the case - they did work, they kept us safe for seven years - or that now somehow the threat's gone away. There's no longer a threat out there, we don't have to be as tough and aggressive as the Bush administration was.
