A Soviet condition for a declaration of war in Japan was an official recognition of China`s Mongolian independence (the Mongolian People`s Republic was a Soviet satellite state from the beginning of 1924 until World War II). The Soviets also wanted recognition of Soviet interests in Manchuria and Port Arthur (but not the Chinese for rent). These conditions were agreed without China`s participation. Stalin took a train from Moscow to Yalta. He controlled the physical aspect of the conference, including listening to foreign guest quarters. This meant that he knew a lot of what they were thinking: it also meant that their whims could be taken into account; After Churchill`s daughter, Sarah, at the Voronzov Palace, where the British lived, mentioned that lemon juice worked well with caviar, a lemon tree laden with fruit appeared overnight at the Orangery. The surveillance did not surprise his British and American guests: Churchill, for example, had been warned that he could not receive his ULTRA messages to Yalta. But he got lemons with his caviar. Churchill had some success at Yalta. One of them was the agreement that France should be invited to occupy an area in Germany and participate in the control commission, a key result given Roosevelt`s determination to limit the length of stay of American troops in Europe.
Less concrete, but nevertheless important, Churchill`s hard stance on the defence of freedom and the rule of law, for example in the drafting of the Declaration on Liberated Europe, which called on the three powers to create free elections and democratic governments. The Soviet Union`s failure to meet its commitments did not diminish Churchill`s efforts to secure them. But he played a weak hand compared to Stalin and even more of Roosevelt. The initiative to convene a second „Big Three” conference came from Roosevelt, who had hoped for a meeting before the US presidential elections in November 1944, but later pushed for a meeting in early 1945 at a neutral location in the Mediterranean. Malta, Cyprus and Athens have been proposed. Stalin, who insisted that his doctors oppose long journeys, rejected these options.  Instead, he suggested meeting instead in the Black Sea city of Yalta in Crimea. Fear of Stalin`s plane also contributed to this decision.  Yet Stalin formally referred to Roosevelt as the „host” of the conference; All plenary sessions should take place in the American accommodation of the Livadia Palace, and Roosevelt, without exception, sits in the center of the group photos (all taken by Roosevelt`s official photographer).
At that time, the Soviet army occupied Poland entirely and held much of Eastern Europe with a military power three times greater than the Allied forces of the West. [Citation required] The declaration of the liberated Europe has little to do to dispel the sphere of influence of the agreements that had been incorporated into ceasefire agreements. In the spring of 1945, Churchill had commissioned an emergency military intervention plan (war against the Soviet Union) to reach a „square agreement for Poland” (an unensible operation), which resulted in a May 22 report that reported unfavourable success rates.  The report`s arguments included geostrategic issues (possible Soviet-Japanese alliance that led to the transfer of Japanese troops from the mainland to the native islands, threat to Iran and Iraq) and uncertainty about land battles in Europe.  The first reaction to the Yalta Accords was solemn. Roosevelt and many other Americans saw this as proof that the spirit of US-Soviet war cooperation would be transmitted until the post-war period. But this feeling was only short-lived.
