I think it's kind of a stretch. You know, it's one thing if somebody working for the U.S. government has sold secrets to the other side, it's another if they have something in their personal life that they're hiding for which they could be blackmailed. Having evidence that they didn't tell the truth to somebody in the same building where they work, maybe it's just the old intel guy, is - it's a problem.

A wild and crazy weekend involves sitting on the front porch, smoking a cigar, reading a book.

Soviet foreign ministers would come in to see the president all the time, routinely. Jimmy Carter stopped that after the invasion of Afghanistan. Ronald Reagan resumed it in 1984, I think. And so the fact of a meeting like that I think is not that big a deal.

No policy has proved more successful in making friends for the United States, during the cold war and since, than educating students from abroad at our colleges and universities.
