Question

The leaders of the us, ussr, and great britain said they wanted to cooperate, so why were negotiations at the yalta and potsdam conferences so difficult?

Answer 1

Each country wanted its own sphere of influence

Answer 2

I think it becomes difficult because they all wanted to have more advantages than anyone else, that became too much for the country that they defeated. The Potsdam Conference became difficult because they have problems on the things that they should do with Germany that they want to completely disarm the country.
