If we don't act now, then we will go back to what has happened before and then of course the whole thing begins again and he carries on developing these weapons and these are dangerous weapons, particularly if they fall into the hands of terrorists who we know want to use these weapons if they can get them.

Understand the causes of terror? Yes, we should try, but let there be no moral ambiguity about this: nothing could ever justify the events of September 11 and it is to turn justice on its head to pretend it could

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.

The Donald Trump phenomenon in the U.S. is mirrored completely by the Brexit phenomenon in the U.K. It's very similar forces. And what is interesting to me is there are two different groups that come together, who don't really agree with each other, but have come together in unity against, if you like, what is perceived as the status quo, or - and certainly what is a more center-right or center-left type of politics.

People divide into groups where they talk to each other, but don't talk across the divide. And yet most of the challenges we face in the world today are challenges that are to do with trade, with technology, with how you make sure that people are properly educated, reform your health care system.
