Question

What differences separated the Soviet Union from the United States in the years following World War II

Answer 1

They said there was an "iron curtian" that separated them. The Soviets were communists and the U.S. was capitalist (and still is).

Answer 2

territorial and ideological basis for different economic practices.

Step-by-step explanation:

After the end of WWII, the world was basically split in two, with the USA representing the Western front and the USSR representing the Eastern or communist bloc. The main divide between these two blocks was ideological in nature, with the western front defending a globally interventionist though democratic regime and the USSR defending an equally globally interventionist regime though this one based on an, in theory, socialist approach to the means of production. These tensions are summarized in the conflict called the Cold War which lasted all through almost all of the second half of the 20th century.
