Where is the OLD Soviet Union in the US?

The "Old Soviet Union" refers to the former USSR, which dissolved in 1991 and comprised multiple independent countries, primarily in Eastern Europe and Central Asia. In the United States, there is no physical location that represents the old Soviet Union, but there are numerous Russian and Eastern European communities, cultural centers, and organizations that celebrate the heritage of the former Soviet states. These communities can be found in cities with significant immigrant populations, such as New York, Los Angeles, and Chicago.
