A respectful answer that does delineate all the shades of communism and shows education. Admirable.

It's not much ironic considering how... fascism-leaning Hungary always was, historically. It was a large faction of Hungarian native politicians who invited Soviet intervention in the first place. The Hungarian secret service at the time also shot at protesters, which escalated the protests. Russia at the time wasn't an entire culprit, that changed with 1968.
