The better-known picture I took at the first meeting with Presidents Reagan and Gorbachev was them sitting in front of a blazing fireplace inside a boathouse in Geneva, Switzerland. "The Fireside Summit," as it was aptly named, was a huge event in the Reagan presidency, arguably its most important. It was there that relations between the Soviet Union and the United States started to thaw. But to me the best and most revealing photograph was taken after the meeting broke up and the two men were putting on their coats. The expression on Gorbachev's face as he looked at Reagan was somewhere between love and admiration. It was the seduction of Mikhail Gorbachev, the Master Communist, by Ronald Reagan, the Master American. It was a romance that culminated in the downfall of the U.S.S.R.
