Over half of these defectors are what you would be considering the intelligentsia, kind of young people that have, you know, spectacular careers ahead of them.

So that just got too much for the ketchup bottle in 1961. And while Stalin never built that Berlin Wall, Khrushchev is going to agree to do it. And that kind of order comes down on August 13, 1961, when, you know, before that date you could get across from East Berlin to West Berlin.
