The British were particularly concerned about the possibility that Stalin might create the largest “Greater Bulgaria” in 1941, when the Germans, along with much of Greek Thrace and Greek Macedonia, assailed Bulgaria to continue after the war.  Greater Bulgaria, created in 1941, had given Bulgaria a coast on the Aegean Sea, and the Soviets most disturbed the British because the Bulgarians remained in the parts of Greece and Yugoslavia they had annexed on the grounds that Bulgaria was now a Soviet ally.  What was even scarier for Churchill was the possibility that the Red Army would head south to Greece and free it, thus putting Britain in front of the fait accompli, to which the eAM was in power.  In a state of despair, on 21 September Eden sent a cable to Sir Archibald Clark Kerr, ambassador to Moscow, to tell him that he hoped “that the Soviet government would not consider it necessary to send Russian troops to part of Greece, except in accordance with Her Majesty`s Government.”  After two anxious days waiting for a Soviet response, foreign Deputy Commissioner Andrei Vysinski Clark Kerr announced on 23 September that the Soviet Union would abide by the Eden-Gusev Agreement of May 1944.  Alongside Greece, Churchill strongly insisted that Bulgaria return to the borders before 1941.  Churchill was particularly indifferent to the annulment of the 1940 Treaty of Craiova, which had given the Bulgarians southern Dobruja at Romania`s expense. After the conclusion of the trade and credit agreement between Germany and Germany, the question arises of the improvement of political relations between Germany and the USSR.  The public part of the Moscow agreement was announced with great fanfare on August 25, 1939, the day Hitler would launch his “flash war” (rapid surprise attacks) eastwards to Poland. Earlier, however, on the same day, Britain and France reacted, knowing that the Naziové agreement was still pending by formalizing their promise to Poland in a treaty that declared that anyone defending Poland would fight if attacked. For Germany an autonomous economic approach and an alliance with Great Britain were impossible, so that closer relations with the Soviet Union became necessary to preserve the raw materials.  In addition to economic reasons, a British blockade expected during the war would also lead to massive shortages for Germany in a number of important raw materials.  According to the Munich Agreements, from late 1938 to March 1939, German military requirements and Soviet demands for military machinery increased.
 The third Soviet five-year plan also required new infusions of industrial technology and equipment.   [Necessary clarifications] German war planners had assessed serious losses of raw materials when Germany was at war without Soviet supplies.  On 16 April 1922, the German Republic of Weimar and the Soviet Union agreed on the Treaty of Rapallo, in which they renounced territorial and financial rights.  Each side also claimed neutrality in the event of an attack on the other with the Treaty of Berlin (1926).  Trade between the two countries declined sharply after the First World War, with trade agreements signed in the mid-1920s helping to increase trade to 433 million marks per year in 1927.  According to Melvyn Leffler, Churchill tried to abandon the percentage agreement after the end of world war and the visit of Greece.  This was particularly the case, with Churchill and Roosevelt keeping such discretion over the agreement that their successors in power did not know it. Meanwhile, Stalin initially believed that the secret agreement was more important than Yalta`s public agreement, which led to his perception of betrayal and the growing urgency to secure friendly governments on the ussr`s border.  Although Yugoslavia was not considered as important as Italy and Greece, Churchill had insisted in June 1944 that a coalition government merge the provisional government of Democratic Yugoslavia
