The biggest threat we face is the possibility of terrorist groups like al Qaeda equipped with weapons of mass destruction, with nukes, bugs or gas. That was the threat after 9/11 and when we took down Saddam Hussein we eliminated Iraq as a potential source of that.

I had a reputation of being somewhat moderate, partly, I think, because I wasn't a 'bomb thrower' like some of my conservative colleagues, and partly because I got along with people all across the political spectrum.

I - obviously, I'm not a big fan of President Obama. I think he's been one of our weakest presidents. I just fundamentally disagree with him philosophically.

I've worked for four presidents and watched two others up close, and I know that there's no such thing as a routine day in the Oval Office.

It’s clearly established in terms of training, provision of bomb-making experts, training of people with respect to chemical and biological warfare capabilities, that al-Qaeda sent personnel to Iraq for training and so forth.

One of the worst things we could do is start to act now as though the attack of 9/11 is a thing of the past and will never be repeated. That's just not true.

His regime has had high-level contacts with al Qaeda going back a decade and has provided training to al Qaeda terrorists.
