I have been to Cuba. In my experience, that's not an accurate description of their homes. And "deep poverty" is a meaningless statement in a country as different as that - despite a lack of wages, Cubans are well-provided for by the government, which is more than can be said of a good part of population in many Western nations.
>USSR never managed to turn to US greatest opponent
This is a very interesting take on world history. What do you consider the USSR's role in the world to be during the Cold War? What makes you reject most modern historical thought?
And there are those in the West who starve. Who better provides for the poor?
>And USSR's role was the same as North Korea today
The US is not currently producing a huge amount of propaganda in a culture war against North Korea. There is no scare of North-Korean-sympathisers infiltrating American society, or its government. The West is not fighting any proxy wars with the Koreans, nor are they engaging in international competitions equivalent to the space race. There is no "North Korean sphere" - North Korea has no cultural or political influence over a broad group of nations around the world. North Korea does not constitute some kind of "fourth world".
And USSR never managed to turn to US greatest opponent, despite killing millions trying.
