"But Tibet!!!" has to be the most intellectually lazy pro-American imperialism argument, particularly when you consider the US history of regime change [1]. Heck, this unwinnable war we're fighting in Iran has a direct through line to not one but two such incidents, specifically the coup in 1953 and US involvement in the Islamic Revolution in 1979 (ie making sure the fundamentalists won instead of the communists). And weirdly a significant number of these puppets end up turning into enemies and far worse problems (eg Saddam Hussein, Osama bin Laden).
Tibet specifically is funny because one of the things China did was end slavery in Tibet [2]. A large percentage of the population were "serfs" but that was a generous translation because these "serfs" could be traded. You know, like property. Like slaves.
And Vietnam? They had a small border dispute. What did the US do to Vietnam? And Cambodia? And Laos?
But the funniest claim of all here is election interference. The foreign interference in US elections conversation begins and ends with Israel with an honorable mention to Russia for running some Facebook ads. Just last night we had a debate in the Democratic primary for Senate in Michigan, a race that AIPAC proxies (eg UDP) have spent upwards of $60 million. On a primary.

Did the US annex Vietnam or Iran?
There's a qualitative difference between interference and outright annexation, with borders redrawn and cultures violently assimilated.
