WASHINGTON, Oct. 8 (UPI) -- I don't think it possible for any historian to visit the Baltic countries or the rest of Central Europe and not reflect on the catastrophes World War I brought for that part of the world. Communism, World War II, National Socialism, the extinction of some communities and the expulsion of others, wholesale alteration of national boundaries, all these and more flowed from the assassination of the Archduke Franz Ferdinand on June 28, 1914. One pebble touched off an avalanche.
