The declaration of the three heads of state and government at the end of the conference on 1 December 1943 listed the following military conclusions: it was given to Stalin, the man of steel, who received it humbly and delivered it to Roosevelt for inspection; It was the latter who provided the drama by brandishing it with the words: “Truly, they had steel hearts!” Stalin could have forgiven seeing this episode as a tribute to his fellow leaders to his superiority as a man who had been fleeing Hitler since the beginning of 1943. On November 28, 1943, at the opening of the first full session of the Tehran Conference between U.S. President Franklin D. Roosevelt, Soviet President Joseph Stalin and British Prime Minister Winston Churchill, the “Three Great” Allies had good reason to be optimistic about the progress of the war against the German-led axis powers. Italy and Japan. This was reinforced by the theatrical climax of the Tehran conference, the presentation of the sword of Stalingrad by Churchill on the second day of the trial. This magnificent ceremonial sword, made especially on the orders of the British monarch, was written as a tribute to the British people with the inscription “To the citizens in the heart of the steel of Stalingrad, the gift of King George VI.” The Turkish president discussed Roosevelt and Churchill at the conference in Cairo in November 1943 and promised to go to war when his country was fully armed. In August 1944, Turkey severed relations with Germany. In February 1945, Turkey declared war on Germany and Japan, which could have been a symbolic step for Turkey to join the next United Nations.  With regard to the post-war period, the governments of the United States, the U.S. S.S.R. and the United Kingdom agree with the Iranian government that all economic problems facing Iran at the end of hostilities agree with those of other members of the United Nations, conferences or international organizations held or created to deal with international economic issues should be fully addressed.
These tensions resulted in the most important topic discussed by the Big Three in Tehran – the nature and date of the launch of a “second front” in northwestern Europe, dubbed “Overlord”, whose initial planning had been launched at the Casablanca conference in January 1943.
