Besides, as far as anyone knows outside of the Fallout games, nobody won. There's no way to measure the immense damage done to anyone in the world.
For all we know, America, China and Russia could have felt the entire brunt of it and the people in Fiji are probably sitting around drinking cocktails while you scavenge around the wastes for burnt dirty crackers.
Until the release authentic lore about other people in the world, I doubt anyone can know much about anything.
P.S Fallout: Down Under. <3 Killeroo's, Monster Spiders and Gigantic Black Snakes, sounds fun.
Well when it states in opening, the world was consumed by nuclear fire. It kinda leads to thinking, that not just America, China, or Russia only felt the brunt of the nukes. I'm quite sure since Fiji isn't all that important, they probably didn't get hit, and are either under miles and miles of water, or all either ghouls or dead from radioactive fallout. But Europe being what it was back then, I'm sure they got hit just as much as America or other places.
