Soviet Disunion

The soviet "union" never existed because it was imperialism: dozens of nations invaded, subjected to genocide, and kept together at gunpoint.

World War II started when the USSR and its ally, the Nazis, invaded Poland. After the war ended, the USSR continued invading even more countries and doomed them to miserable poverty and underdevelopment.

The same happens in China today: it is an empire. The Chinese language doesn't even exist. China is made up of thousands of nations with thousands of languages that are mutually unintelligible and hate each other. In western China, they are white, Caucasian.
