I see big difference in between countrys at that time, while USA was in a facet where it was fighting more about rigths and fredom, a serie of events that will form the american future, they were changing their form of living, while Soviet Union was still working to aquire and delimit territory. SU keep fighting about owning and let go lands, you don´t see so much relevant events about fredom and comute between society, while in USA all the events were society related, Market Crash made a huge impact in the country, people were reforming their fredom and changing they way of thinking, making things happend togheter, seem like SU were not interested in their people.
