The 2015 dystopic Occupied/Okkupert (TV Series) seems that would have pretty dramatic and far reaching Althistorical consequences. And,chiefly among them,IMO, would be the virtual dissolution, as matter of fact, of the NATO and/or the Atlantic/European mutual security/defense treaties agreements as well as the US foreign defense policy:
I remember criticizing that premise as completely ASB. I'm honestly not sure which of the underlying assumptions strikes me as more idiotic:
1) The EU would be desperate enough for oil to get mad at Norway for shutting down its oil fields.
2) The EU would decide that the best solution to this is to overthrow the Norwegian government, instead of trying to negotiate an alternative, find another buyer, or something similar.
3) The EU would decide that instead of invading Norway themselves, it's a good idea to outsource the job to Russia.
4) Russia would decide to do the EU this favor literally for nothing, eating all the "badboy" themselves. Instead of, I don't know, maybe sell their oil to the EU?
5) Russia somehow manages to stage a successful invasion of Norway. Which requires ignoring minutiae like they'd have to transport the entire expeditionary force by sea (through the bloody Arctic, no less), or go through Sweden and Finland (that's just not going to happen).
In terms of plausibility, you could tell me that Germany staged the Unspeakable Marine Mammal, and it's just as believable.
6) Assuming that, by some ASB miracle, these five assumptions are achieved…the reaction of the rest of the world is to just sit back and watch. Nobody does anything.
