"Now, let's fast forward ahead to post-World War II... Now, the Soviet Union, they did not have two massive oceans on their West Coast and East Coast like United States did. Because of this, they wanted to create a buffer zone between Western Europe and the Soviet Union. So how they did this is that Soviet forces, they occupied Eastern Europe, and you can see they're occupation based on the purple and the shade of purple, and they set up puppet governments in those countries. Now, what we're talking about in puppet governments is that the government in those countries, let's say Eastern Germany right here, those government officials there were controlled by the Soviet Union located here. That's what we mean by puppet governments."

It says directly and exactly: "...what we're talking about in puppet governments is that the government in those countries, let's say Eastern Germany right here, those government officials there were controlled by the Soviet Union"
