I've met quite a few dictators up close and personal in my life.

The absence of Saddam is a huge weight off the Arab world.

Saddam Hussein had nerve gas and used it against his own people, he had used chemical weapons against the Iranians and he almost had a nuclear bomb in 1981 and in 1991. And he had been caught with anthrax in 1995 by the UN inspections after denying that he had it.

We are already seeing a degree of instability in the world because Obama seems to have consciously wanted to step back. Donald Trump is going to be "Obama squared," a more extreme version of the same thing.

After a regime is removed, however, it is dangerous to leave a security vacuum.

There's a lot of money to pay for this ... the oil revenues of that country could bring between $50 and $100 billion over the course of the next two or three years...We're dealing with a country that can really finance its own reconstruction, and relatively soon.

I certainly think it's important to speak up and say how unacceptable Donald Trump is. I'm always more than willing to do that.
