The Tehran Conference, which took place in November 1943, was a meeting of the leaders of the Allied Powers during World War II. The conference, which was held in Tehran, Iran, was attended by the leaders of the United States, the United Kingdom, and the Soviet Union. While the conference was seen as a successful meeting, there were a number of disagreements that occurred.

One of the main disagreements at the Tehran Conference was over the issue of opening a second front in Europe. Joseph Stalin, the leader of the Soviet Union, had been calling for a second front for some time, as he believed that the Allies were not doing enough to help the Soviet Union in its fight against Germany. However, Winston Churchill, the Prime Minister of the United Kingdom, was hesitant to open a second front, as he believed that the Allies were not yet prepared for such an undertaking.

Another area of disagreement at the Tehran Conference was over the issue of Poland. The Soviet Union had already taken control of Poland, and Stalin was determined to keep it under Soviet control. However, both the United States and the United Kingdom were opposed to this, and there was heated debate over the issue at the conference.

Finally, there was disagreement over the future of Germany. The Soviet Union was determined to punish Germany severely after the war, while the United States and the United Kingdom were more concerned with rebuilding the country and preventing the rise of another dictator. While these disagreements were never fully resolved at the Tehran Conference, the Allies were able to come to a number of important agreements, including the opening of a second front and the formation of the United Nations.

In conclusion, while the Tehran Conference was a successful meeting of the Allied Powers, there were a number of disagreements that occurred. These disagreements centered around issues such as the opening of a second front in Europe, the future of Poland, and the future of Germany. Despite these disagreements, the Allies were able to come to a number of important agreements that helped to shape the course of the war and the post-war world.
