The biological agents we believe Iraq can produce include anthrax, botulinum, toxin, aflatoxin and ricin. All eventually result in excruciatingly painful death.

Can we be sure that terrorism and WMD will join together? If we are wrong, we will have destroyed a threat that, at its least is responsible for inhuman carnage and suffering. That is something I am confident history will forgive. But if our critics are wrong and we do not act, then we will have hesitated in face of this menace, when we should have given leadership. That is something history will not forgive.

The kaleidoscope has been shaken. The pieces are in flux. Soon they will settle again. Before they do, let us re-order this world around us.

You wouldn't be human if you didn't feel both a sense of responsibility and a deep sadness for those who have lost their lives.

I think most people who have dealt with me think I'm a pretty straight sort of guy, and I am.

I think we've, again, got to be extremely careful; otherwise we'll misunderstand what's going on in Iraq and in Syria today. Of course, you can't say that those of us who removed Saddam in 2003 bear no responsibility for the situation in 2015.

What I will say to people is what you require are rules and not prejudices.
