I say the elite looks out of touch because it's kind of saying; look we'll manage all this for you. You know, we know best. We'll sort it all out for you. And then because people believe that doesn't meet their case for change and they want real change, social media and the way the relationship between people can come into a sense of belonging very quickly, that then is itself a revolutionary phenomenon. You see this around the world.

I mean, you can agree or disagree with Iraq or Afghanistan, but by the way, now the great campaigning cause out there is the absence of intervention in Syria. And then in Libya, it's partial intervention. And that doesn't really explain why some countries that have literally nothing to do with the interventions in the Middle East end up getting targeted.

There are unquestionably links between al-Qaida and Iraq.

My view always is that we should learn the lessons, both of the last sort of 50 years of policy-making and it is possible to get to a foreign policy that is engaged and active without going back to where we were in the post-9/11 world.

I had discovered long ago the first lesson of political courage: to think anew. I had then learned the second: to be prepared to lead and to decide. I was now studying the third: how to take the calculated risk. I was going to alienate some people, like it or not. The moment you decide, you divide.

But in terms of how people live together, how we minimize the prospects of conflict and maximize the prospects of peace, the place of religion in our society today is essential.

We, therefore, here in Britain stand shoulder to shoulder with our American friends in this hour of tragedy, and we, like them, will not rest until this evil is driven from our world.
