I think it's important for people like me to evaluate and reevaluate.

The evidence about Saddam having actual biological and chemical weapons, as opposed to the capability to develop them, has turned out to be wrong. I acknowledge that and accept it. I simply point out, such evidence was agreed by the whole international community, not least because Saddam had used such weapons against his own people and neighbouring countries.

Be a doer and not a critic.

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.

After the terrible events of last week, there is still the shock and disbelief; there is anger; there is fear; but there is also, throughout the world, a profound sense of solidarity; there is courage; there is a surging of the human spirit.

We are going to expand enormously -- our economy, our consumption, over the years to come ... But the consequences of that on emissions are going to be severe unless we change direction.

The art of leadership is saying no, not saying yes. It is very easy to say yes.
