Ok, but if that’s the case, why are we drawing a line at a nation’s internal population and disregarding their external policies? The USA killed three million people in the War in Iraq, including Iraqis who were very critical of the American presence. The USA has assassinated Latin American presidents for speaking out against the USA and replaced them with more America-friendly dictators. And yet everyone who talks about authoritarianism doesn’t include western nations in their discussion, they instead make up a cartoon idea of what countries outside the west are like. Your definition of what is or isn’t tankie/authoritarian has some kind of nationalist bias built into it.
Every time someone describes what authoritarianism is, it makes me think that America and the EU are the worst perpetrators of this behavior, but they mainly export all their violence rather than use the worst of it domestically. Domestically they use private sector means to distribute violence, such as poverty, prisons, and the facilitation of ambient racism.
This reminds me of the dividing line that liberals use, which is when they say things like “that dictator killed HIS OWN PEOPLE.” As if killing people externally is more excusable crime?
