Hitler, and probably no one else, realized that if the French and Britons had mobilized after the militarization of the Rhineland, Germany would have been defeated. The Germans really didn't have the manpower to defend the territory and hadn't stockpiled enough war materiel to wage an effective war. Too, the "Volkswagen" ripoff of the German people hadn't fully paid off yet.....The Allies stalled for far too long.......
Historians usually blast Chamberlain as a political figure, but he did prepare Britain for the coming war...
Further, I personally believe that Pro-Nazism (or, at least support of "Germanic solidarity") throughout the world had a significant and telling effect on the European policy of appeasement. People, in general, conceded that germanic peoples had the right to be unified as one nation. For heavens sake, the Czechs had absolutely no say about the future of the Sudetenland, and the territory was part of their country!!!
Sorry! I didn't mean to turn this post into a historiographical discussion.........
