In the Olympics, as in the world, the dominant forces are the U.S. and the Soviet Union. One or the other will "win" the Olympics—that is, capture the most medals, raise its national flag the most times, hear to the point of embarrassment the repeated playing of its national anthem. Germany—which fields two teams this time, one East and one West—will be close behind, and other traditionally strong nations will follow along. But the Olympics are changing. More and more, the so-called lesser countries are moving into the Olympic spotlight, and others are making an impact in events that historically have not been their province. Imagine a Colombian threatening the European monopoly on cycling medals, or an Italian vaulting nearly 17 feet, or a Yugoslavian basketball team seriously challenging the U.S. Here is a Finn with a world record in weight lifting. Finns run, they don't lift weights; no Finn has ever won so much as a bronze in Olympic lifting. But there he is. The times are changing. The athletes shown on these pages are not sure-pop medal winners—no one is at an Olympics—but they are coming on. They matter. Watch for them.
