A surprising state of affairs Felix, was Chamberlain incredibly daft, or was he trying to buy time for Britain to re-arm?
I favor the idea that he and Daladier actually thought they were dealing with a gentleman in the old sense, where there were certain "niceties" observed between Men of Power and Responsibility (Mr. Hitler and Co. could put on a charming presence when necessary), plus there was no stomach for another European War (WW1 was still very fresh in the minds of many, and the Spanish Civil War, a warning of things to come, was barely winding down).
