Why the contradictions between Germany and the USSR intensified.

Two absolutely opposite ideologies could not fail to cause a military conflict between the USSR and Germany. Nazism recognizes only one, the Aryan nation, and all the rest must be oppressed. In socialism, the nation does not play a role, so all people should be brothers. In addition to all of the above, Hitler was going to expand the “living space” of the country by moving east, to the borders of the USSR, where he planned to use the country of the Soviets as a supplier of oil and agricultural products.
