I just want to say this. I want to say it gently but I want to say it firmly: There is a tendency for the world to say to America, ‘the big problems of the world are yours, you go and sort them out,’ and then to worry when America wants to sort them out.

I'm one of these people that, once you have had your election and you have elected your candidate, let's see what actually happens.

Repressive states are developing weapons that could cause destruction on a massive scale.

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.

As for those that carried out these attacks there are no adequate words of condemnation. Their barbarism will stand as their shame for all eternity.

Do I know I'm right? Judgements aren't the same as facts. Instinct is not science. I'm like any other human being as fallible and as capable of being wrong. I only know what I believe.

My office is on Twitter. I don't tweet myself - at least, not intentionally, but I probably should do.
