Having been around at the time, that is an interesting post.
Hitler told his staff that, IF THE FRENCH CAME IN FORCE FROM THE WEST HE WOULD HAVE TO RUN FOR HIS LIFE, all would be lost.
However, Hitler knew the French were cowards and he was right. When the French did NOTHING the Russians jumped in from the east and took most of Poland.
WWII was then set in concrete because of the damned cowardly French.
