The threat today is not that of the 1930s. It's not big powers going to war with each other. The ravages which fundamentalist political ideology inflicted on the 20th century are memories. The Cold war is over. Europe is at peace, if not always diplomatically.

I always say, when they ask me about American politics, is for you guys to decide who you elect.

There is good evidence that last year's European heat wave was influenced by global warming. It resulted in 26,000 premature deaths and cost $13.5bn.

I'm an avowed centrist, and I believe that - centrism is often - it's almost the wrong word to use, because it's often seen as sort of splitting the difference between right and left.

The socialism of centralised state control of industry and production, is dead. It misunderstood the nature and development of a modern market economy. It failed to recognise that the state and public sector can become a vested interest capable of oppression as much as the vested interests of wealth and capital. it was based on a false view of class that became too rigid to explain or illuminate the nature of class division today.

I happen to think it's the politics that makes you electable, but the reason for that is politicians sometimes talk about electability as if it's just a matter of conning the public. Actually, it's a matter of persuading the public, and in my experience, usually, the public gets it right.

I think, there is a possibility - I would say it's more than that - that we will come to a view of foreign policy going forward that learns from the past but doesn't get captured by it.
