"You know already that I have done all that one man can do to compose this quarrel. After my visits to Germany I have realized vividly how Herr Hitler feels that he must champion other Germans, and his indignation that grievances have not been met before this. He told me privately, and last night he repeated publicly, that after this Sudeten German question is settled, that is the end of Germany's territorial claims in Europe."
