Communism

Undeniably it was a bad thing that the Soviet Union fell. 7 million people died because of it falling, and we lost one of the most progressive countries from an international perspective. Never has a country been so firmly dedicated to anti-Imperialism and decolonization with the actual real power that the Soviet Union had to back that up, it not only came with huge victories for the working class internally, but also supported Cuba, Palestine, Algeria, Korea, China, defeated the Nazis (90% of Nazis killed during WWII were from the Soviets), and more.

So yes, the USSR falling was a bad thing.
