US politics is plagued by American exceptionalism. The overwhelming majority of the population do not even consider how people in other countries view things, and they implicitly assume their own Overton window is the global Overton window of "reasonable discourse." If anyone disagrees, they literally cannot fathom it is even possible to disagree with American politics, that literally cannot even register in their brain as a possibility, thus they assume you must either be lying or paid to disagree ("wumao" or "Russian bot"). This is why Americans are often so easy to convince that the US should intervene in other countries, because they nearly all implicitly believe that even the citizens of countries like China or Cuba also believe in American politics and are secretly hoping for Americans to come liberate them but are forced to lie about it by their government.

Honestly, I see no way to break this mass delusion without something seriously calling into question American exceptionalism, something that forces Americans to actually take seriously their own position in global politics, which is something I doubt can come internally from the US. It would have to come externally: something in the global geopolitical situation would have to change to force Americans to take seriously the diversity of global politics. It doesn't even matter if what it is is "socialist," there just needs to be something that breaks the illusion that US-style politics is the only way to understand the world and the only valid system. You aren't going to have much luck convincing a population of socialism in a capitalist country where suggesting anything outside of its own media Overton window is considered extremely taboo (which is ironic because if you ask most Americans straight-up if they trust the media, they will say no, but they will almost always defend everything the media says verbatim and act like it is absurd to question it).
