The correct answer is B) Each country had its own agenda about the post-war world.
The correct question should read: The leaders of the United States, the USSR, and Great Britain said they wanted to cooperate, so why were negotiations at the Yalta and Potsdam conferences so difficult?
The other options were A) The leaders were not honest about their goals. C) Germany and Japan were still seen as a threat by the Allies. D) The end of the war was still far away.
So negotiations at the Yalta and Potsdam conferences so difficult because each country had its own agenda about the post-war world.
It all came down to political and economic interests for each of the above-mentioned countries. The Soviet Union, in particular, was not satisfied with the negotiations regarding territorial control. That is why Joseph Stalin started to spread Communism in many Eastern European countries such as Czechoslovakia, Poland, Albania, Hungary, East Germany, and Rumania.
To protect its head start, Britain tried to enforce strict rules against exporting inventions.
