ABSTRACT
The Tehran Conference, which was devoted primarily to discussion of military matters, also focused on the question of Poland's post-war frontiers, even though Churchill had no power from Parliament nor Roosevelt from Congress to define post-war frontiers. Indeed, before Tehran the talk among the Allies had been limited to the possible detachment of East Prussia, Danzig and Upper Silesia; nothing more had been seriously considered. Half a year after the Tehran Conference, in May 1944, the Committee on Post-War Programs in the State Department prepared a memorandum containing policy recommendations with respect to the treatment of Germany in the light of long-term United States interests. In a memorandum written a full six weeks before the Yalta Conference, Kennan expressed his misgivings with a frontier arrangement which makes unrealistic the idea of a free and independent Poland.
