I'm more targeting this at everyone than just you, but it needs to be said again.
The rest of the universe didn't turn out as anything but ashes! Europe blew itself to hell, then got nuked. The Middle-East and Africa were destroyed by Europeans fighting over them. Australia...what about it? It likely got nuked just the same as anyone else, but there was nothing interesting going on over there anyway. Ditto Russia and the other Eastern European countries.
China got smashed by the entire U.S. arsenal. If anything is left, it'll only be a small section of it like New Vegas. And even then, canon has already stated that the Chinese already tried to rebuild, and collapsed again. There isn't really anything left, no factions or anything. It would be as if the Enclave took over the Wasteland, and then they all got killed by raiders.
People aren't saying that the series shouldn't leave America because they are American nationalists who want to keep it to themselves, we are saying it because the story really can't work outside of America due to both thematic and logical reasons. You are operating under the false assumption that a Fallout set in your location of choice could still retain Fallout's distinct (and already discussed, American) feel while somehow incorporating your country's culture and such. It simply can't be done. Either you end up with a game that is just Fallout with some labels moved around, or something that simply isn't Fallout. And I'm pretty sure you don't want either of those.
