Why disperse?

[Navaron]

Ok,

Heres a little storyline question. Why are all 3 of the factions on different continents? What made them disperse and unify in the same area? How did they get the people who opposed them out of the area? I know that the democrats, republicans, and green party didn't divide the country into thirds last election (its a metaphor, let it go)?

Don't we also have to assume that all people on the planet are soldiers? There are no cities or refugee camps in the game, just military bases. So can we assume there was a clarion call for all able bodied people to join the world wide struggle? That would explain the geographic bases (the empire ones that don't change hands).

I don't know
