So the Soviets who were invading from the East, they're going to get their paws on East Germany and then three of the other allied powers, Britain, France, and the United States, are going to control the sectors in West Germany. However, Houston, we have a problem. And that would be, you Berliners, Berlin, the capital is also going to be divided because it's the administrational capital of Germany. So it sits 96 miles deep into the red, deep into East Germany, which is occupied by the Soviets. So in Berlin itself, you have basically East Berlin, which is controlled by the Soviets, and then those other three allied powers, Great Britain, France, and the United States are controlling West Berlin. So eventually that's where the wall is going to be dividing, not only East Berlin from West Berlin, but wrapping itself around with other East German states around West Berlin. So West Berlin is going to be encircled by this wall.
