Well as the horrors of the 20th century go, that was one of the worst and self-induced. I mean you can think of the starvation of Ukraine as a stab of nationalism (Georgian, Russian) but Mao kills his own people. I assume it overlaps with a famine that might have taken him out of power.
Good to compare and show people that this is how Mao and Pol Pot START but OMG does the regime neither have the stomach nor the balls to go the whole way. And the US does have semi-autonomous regions with their own political protocols. That will always block some thuggery.
Restive provinces.
Out of curiosity what makes you think they don’t have the stomach or balls to go the whole way?
Because they don't. You just have to look at them. But the institutional barriers to sort of takeover executed by Mao, Mussolini, Hitler, Stalin etc did in their respective cases are quite large starting with the fact that the FBI are simply not a secret police and that there are fifty--5 OH--
independent administrative jurisdictions where the Gov is the CO of the only approximate militia. But come on? The people in the White House are not Serious People. They have never even lead a movement to crash a party, let alone beer hall putsch (Hitler) or numerous revolutionary actions (Stalin)-
And the toddler in charge just wants money. The Song of Hate he sings has succeeded but he has no more idea what it means than what being President means.
