OK, but what about the open stuff? Like the current and previous president being publicly genocidal? Like the health care system being used as a weapon against the domestic population, or the US armed forces destroying the planet by just existing and spewing so much carbon oxides and pollutants into the global environment?

Either those votes are worth something, and it implicates US voters, or they're not worth something and the US political system is basically a sham deserving of revolution, which also implicates US voters who do not organise to this end. Arguably every state on friendly terms with the US is similarly morally implicated as well.
