So why does the wall go down? It goes down because communism goes down. That's the short answer. But certainly the American position was always to not have that wall. Although when it first went up, we should say that JFK was probably kind of relieved. Because remember, the biggest fear was that Khrushchev was going to invade West Berlin or West Germany. So the idea that he gave up and he was going to build a wall to keep his people in seemed pretty groovy at the time.
