One thing I wish had been better shown in the as-released The Power Fantasy is what the geopolitics are for the non-US places. (Spoilers up thru #16)
Like. After the Major gets turned into a golf ball, the US officially has zero ability to play global peacekeeper; at best they have nukes they might get to use as retaliation against other supers. Maybe.
Other countries are non-players entirely, things to not be fought but merely fought over. Thus, unshown and unconsidered, when it comes to opinions.
So... What's that like? What is the day to day politics and society, in the places where the real-world balance of forces produce ethnic cleansing or second-class citizens or open corruption?
There's an obvious tension where none of them can outright declare themselves Emperor of Earth and make declarations all must follow; but I also can't see any of the petty dictatorships or caste systems of the late 20th century lasting long when every major actor is, at worst, a liberal.
Now, you could interpret this as another layer of the nuclear powers thing; the world outside of the Superpowers gets ignored because how those places do is secondary to whether The Heavy stubbed his toe that morning. But the interactions between real-world nuclear powers is significantly different from TPF's supers: The USA's interests and power are actually tied, to some extent, to who is ruling in Iran. China entered North Korea not just because they ideologically supported Communism but because an American Ally on the border is a threat.
Meanwhile this doesn't apply in-universe: exactly one Superpower has his power depend on outside support and he kept that secret well enough to bluff for a decade. Lux needs puppet bodies to keep his brain safe under NYC, but otherwise does not need the world going in a particular direction to keep his power. The things they push for are preferences, not needs; the opposite of Realpolitik, in some sense.
So is the rest of the world... Nice? Are they all shitty-at-worst democracies, various flavours of communist or capitalist or whatever, but nowhere the government can openly torture homosexuals or slaughter protestors?
I can theorize about this—maybe Dev, deciding to push against Rule by Supers over Anarchism, ended up propping up dictators the others didn't like. Would explain why everyone calls him a Nazi. Maybe Santa "Metaphor for the Liberal Internation Order" Valentina stopped The Heavy from doing regime change. Who knows.
Maybe this just where the metaphor, like all metaphors, stretches past the point of usefulness. That's fine, it's a fantastic allegory at what it's doing and it's fine that it can't handle every fiddly detail; certainly the arguments it's making work in the framing it's using. Still,....
Here's my suspicion: the scene early on, where Tonya is being interrogated, implies that a) police brutality against Atomics exists and b) those same cops aren't afraid of psychic retaliation because they all wear psychic alarms. They don't work, if Lux is really trying, but they sure act like they work.
The implication, in my mind, is that Lux is going thru the worst cases of police brutality and quietly killing the worst offenders, and Valentina is quietly accepting this as a compromise from "everyone is mind controlled into not being a dick". Cops that rough up a random atomic, arrest them just to pad hours, think they're safe; the ones that rape detainees get selected against. It's a silent improvement, a balance between stopping the abuse and becoming Superdictators.
Probably the rest of the world is like this—you can be Silvio Berlusconi but not Saddam Hussein, because anyone who looks like they're going to order a genocide once in power dies years beforehand.
Which ties into the thing where half the Superpowers are constantly doing deniable shit another one of them knows about and dislikes (Dev and the "Inverted Pyramid" supplying the KillSat to the US; Lux quietly letting Nixon nuke Valentina) that they can't outright accuse each other of without risking Armageddon. Spycraft shit, because it's all Cold War.
