I think the best parallel that could be drawn would be the [Kent State Shootings.] (https://en.m.wikipedia.org/wiki/Kent_State_shootings) given the similarities between the Kent state students’ goals and the Tiananmen students’ goals.
Though even then there were only four fatalities. No where near Tiananmen. Plus the US government isn’t doing anything to try to hide the murders either.
Um. This is just flatly not true. For starters, according to the Chinese government themselves only 23 military personel died. And those casualties only occurred AFTER the peoples liberation army started using live rounds against protesters the evening of June the 3rd 1989. And the 300 number is very conservative. The actual number is likely in the thousands.
You very clearly are either a troll just making things up or you have absolutely no idea what you’re talking about
