There isn't much point arguing about the word "libertarian." It would make about as much sense to argue with an unreconstructed Stalinist about the word "democracy" - recall that they called what they'd constructed "peoples' democracies." The weird offshoot of ultra-right individualist anarchism that is called "libertarian" here happens to amount to advocacy of perhaps the worst kind of imaginable tyranny, namely unaccountable private tyranny. If they want to call that "libertarian," fine; after all, Stalin called his system "democratic." But why bother arguing about it?

Look at the ozone story. As long as it was the southern hemisphere that was being threatened, there was very little talk about it. When it was discovered in the north, very quickly actions were taken to do something about it. Right now there's discussion of putting serious effort into developing a malaria vaccine, because global warming might extend malaria to the rich countries, so something should be done about it.

The public is easily amenable to lies: the more lies there are, the greater the support for war. For instance, when the public was told that Saddam Hussein would attack the U.S., this increased support for the war.

In general, I think, U.S. policies remain constant, going back to the Second World War. But the capacity to implement them is declining.

I think the activism of the 1960s had a very definite civilizing effect on the whole society in all kinds of ways. So lots of things that by now are almost taken for granted were heretical in the 1960s. We had anti-sodomy laws until not many years ago.

Sooner or later, jihadist-style terror and WMD are going to come together and the consequences could be horrendous.

After World War II there were many Jews who remained in refugee camps...President Harry F. Truman called for the Harrison Commission to investigate the situation in the camps and it was a pretty gloomy report. There were very few Jews admitted into the United States.
