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.

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".

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 started work on my first French history book in 1969; on 'Socialism in Provence' in 1974; and on the essays in Marxism and the French Left in 1978. Conversely, my first non-academic publication, a review in the 'TLS', did not come until the late 1980s, and it was not until 1993 that I published my first piece in the 'New York Review.'

Above all, the thrall in which an ideology holds a people is best measured by their collective inability to imagine alternatives.

Social democracy does not represent an ideal future; it does not even represent the ideal past.
