"It would assist us if the Chancellor could state his position about...Locarno. Hitler declared that the German Government would "scrupulously and faithfully observe every treaty into which they had entered of their own free will, including Locarno." The world must not expect to obtain Germany's signature on all occasions, but Germany's signature, once given, would be honoured. No assurance could have been firmer or more specific, if it could be believed. The argument was also clear enough. Hitler did not regard the Versailles Treaty as binding, because it had been signed under duress, but I thought at the time that Hitler might be genuine in this distinction and that he could intend to observe treaties "freely" signed by Germany. This possibility remained in my mind until the occupation of the Rhineland destroyed any further confidence I might have had in Hitler's statements."
