Question

Why do you think that the United States has a positive relationship with Vietnam today, yet maintains no relationship with Cuba? Remember, they are both still "communist" societies.

Answer 1

Vietnam was long and very cost consuming conflict between U.S and Vietnam(communist regime). Due to very long distance and time duration, it was one of the longest conflicts between nations. It was more the conflict of ideology than territory.

But on the other hand, Cuba is a neighbouring country of U.S which share its border with the U.S.

There are many unsolved issues and conflicts between both of countries. A relationship between U.S and Cuba are not very good.

Hence, that is why, the United States has a positive relationship with Vietnam today, yet maintains no relationship with Cuba.
