There was something going on the cafe society of Paris during the 1930's. Americans like William L. Shirer commented on it. A blase sort of atmosphere where no one cared about anything, and don't tell them about problems. Sartre's "existentialism" was a later outgrowth of that. It would appear that the French leaders don't want to fight anymore, but they still want to control things. World War I, fought on French territory, shocked the hell out of them and they drew the wrong conclusions.
