We know, or we think we know, what happened in 1945, and therefore President Reagan travels to Europe this month. There was triumph, we remind ourselves on the fortieth anniversary of the Allied victory, but there was also the revelation of Dachau. We also found Hitler, and now we live with Hitler, remembering other names that have become entangled with his: Auschwitz, Buchenwald, Mylai. the Gulag…. Small wonder, then, that the terms of warfare preoccupying us today are terms of complicity and noncomplicity, terms such as “collaboration” and “resistance.” (Reagan himself thinks nothing of comparing the Contras of Nicaragua to the heroes of the Maquis.) Preoccupied by such terms, we are bound to think of France, of Occupied France and the Vichy.
