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".

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

I grew up in a world where the social democratic state was the norm, not the exception.

I can still boss people around. I can still write. I can still read. I can still eat, and I can still have very strong views.

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.

The rottenness of politics in Yugoslavia didn't come as a surprise. The main lesson is that this is a war which could have easily been stopped by Europe. What was lacking was any will to do so. It's an irony of the achievement of Europe that it had lived for 40 years under the assumption of the unimaginability of internal wars, so it didn't know what to do with it when it was confronted with one close up.

It's important to remember that World War II was experienced very much as a continuity in that sense. Most of World War II in most of Europe wasn't a war; it was an occupation. The war was at the beginning and the end, except in Germany and the Soviet Union, and even there really only at the end. So the rest of time it's an occupation, which in some ways was experienced as an extension of the interwar period. World War II was simply an extreme form, in a whole new key, of the disruption of normal life that began in 1914.
