The Second World War had a precipitating effect in that it discredited the empires, as well as bankrupting them. Not only could you no longer, if you were a colonial subject of France in Africa, look to France as a model of power and influence and civility after what had happened in the war. Nor could the French any longer afford to run their empire. And nor could the British, although they were not discredited in the way that the French were.

Reality is a powerful solvent.

I worry that we have forgotten that the de-ideologized, de-politicized, uncontentious public space of the last 50 years as Europeans have experienced it is not the normal human condition. We shall be sorry to have abandoned a little too quickly the institutions that were set up by our parents and grandparents to protect themselves against a return of the bad old world. Because the bad old world can still come back to haunt you.

I do think we're on the edge of a terrifying world, and that many young people know that but don't know how to talk about it.

I don't believe in an afterlife. I don't believe in a single or multiple godhead. I respect people who do, but I don't believe it myself.

Yugoslavia served as a reminder that the lessons of World War Two were only partially learned. There's a great line someone wrote in the middle of the 1990s, at the time when Clinton was agonizing about whether or not to go into Bosnia: "Everyone says, 'Never again. Never again.' But all they really mean is never again will Germans kill Jews in the streets of Warsaw".

All modern U.S. presidents are perforce politicians, prisoners of their past pronouncements, their party, their constituency, and their colleagues.
