We have some experience with the former Soviet Union, and there were a number of occasions when Soviet citizens came to the United States to study. The effect was dramatic in terms of changing their view of the world. All of them went back to the Soviet Union, and some of them went back to work for the KGB, but they all had a different view of the United States because they had been in the United States studying.
Over time, we have seen what has happened to those people, particularly since the Soviet Union disappeared in 1991, and the effect of these people having some sense, some idea of what was going on outside, was extremely useful, extremely important. I think it's important that we do this.
Here is another example: one of the people who visited the United States and spent some time looking at different parts of our country was the last white president of South Africa. As a young man, he came to the United States, where race relations were very different from what they were in South Africa. I'd like to think that the effect of seeing what happens.... Our record on race relations is certainly not without its flaws; nonetheless, he went back to South Africa with a different view of the world. I don't think that people who come to Canada or the United States from a country like North Korea are going to go back and not be affected by what they see.
