Like I wrote: Tiananmen Square was a fight between two communist factions.
“UK Prime Minister, Margaret Thatcher, expressed “utter revulsion and outrage”, and was “appalled by the indiscriminate shooting of unarmed people.” She promised to relax immigration laws for Hong Kong residents.” (Wikipedia) I might add some of the countries which rationalized or downplayed the massacre were totalitarian or tyrannical states: Burma, North Korea, East Germany, USSR, Cuba, Albania,etc.
