I cannot think of any circumstances in which a government can go to war without the support of parliament.

Today the impulse towards interdependence is immeasurably greater. We are witnessing the beginnings of a new doctrine of international community.

There's a huge wave of anti-establishment feeling. There's an enormous amount of anger. And it's collapsing governments and political movements across the world right now.

Sometimes people say to me, 'Well, what was the difference between Kosovo, which was a successful intervention, and Iraq and Afghanistan that have been so difficult?' And the answer is perfectly simple. In Kosovo, you have, after the removal of the loss of its regime, you had a process of political and economic reconstruction that took its part without the intervention of terrorism. If you had the intervention of terrorism, by the way, it would have been extremely difficult there - but we didn't.

The full horror of what has happened in the United States earlier today is now becoming clearer. It is hard even to contemplate the utter carnage and terror which has engulfed so many innocent people. We've offered President Bush and the American people our solidarity, our profound sympathy, and our prayers. But it is plain that citizens of many countries round the world, including Britain, will have been caught up in this terror.

The moment you stigmatize a whole group of people - for example, Muslims - then, obviously, you make the decent, law-abiding Muslims feel as if they're under threat in some way or that their legitimacy, as members or citizens of society, is brought into question.

You've got problems in Central Asia. And you've got problems within our own communities back home. So if we end up saying, look, this has nothing to do with Islam or it's got no connection with that broader question, then we look, frankly, as if we're in denial about the problem. And the interesting thing in the Middle East is that they have absolutely no problem there in identifying that as Islamist extremism and calling it that.
