I must say a few words her concerning the solution of the Polish problem... Groeber has posed the question: Do I not overestimate the value of the military guarantees? Are not political guarantees in connection with good relations between Poland and Germany far better and more durable than it is possible fo military guarantees to be?... The past conduct of the Polish fraction in the Reichstag and the House of Deputies, and the attempts to have the German Ostmark question discussed as a question of international importance at world peace congresses, do not give my political friends a sufficient guarantee to think that future relations between Poland and Germany can be based solely on a formal paper friendship.
