It's weird how in so much of post-apocalyptic fiction, the focus is on what happens after the proverbial nuke goes off... but only in America. The rest of the world is given pretty summary treatment.
The apocalyptic scenario would shift the power structure of nations: economic or military strength, global alliances, political power etc.
Odd that science fiction is able to set constraints of the current time aside (particularly re. science/technology), but struggles to do so with the state.
