If you look at say, England and Germany a century ago, which had the most advanced navies then, they were dealing with extremely tricky technological problems. Putting a huge gun on a moving platform and ensuring that it could hit another moving target was one of the hardest technical problems of the early twentieth century.

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?

Actually, the phrase "national security" is barely used until the 1930s. And there's a reason. By then, the United States was beginning to become global. Before that the United States had been mostly a regional power - Britain was the biggest global power. After the Second World War, national security is everywhere, because we basically owned the world, so our security is threatened everywhere. Not just on our borders, but everywhere - so you have to have a thousand military bases around the world for "defense."

I happened to go to a school when I was a kid and that's all we did, pursue our own interests. It was kind of structured so you ended up knowing everything you were supposed to know, arithmetic, Latin, whatever it was. But almost always it was under your own initiative.

I suspect most likely that more Nazis came to America. I was a student at Harvard during the early 1950s. There was practically no Jewish faculty there.

When Nazi emissaries came to the United States, they were welcomed at Harvard.

The United States is unusual among the industrial democracies in the rigidity of the system of ideological control - 'indoctrination,' we might say - exercised through the mass media.
