expansion

most if not all countries will expand their territories to clusters of space stations and billions of people will live in those habitats 

when every country has a bigger population in clusters of space stations than their population in their territories on earth, 

then those countries will become more like capital cities representing their territories in space consisting of clusters of space stations 

if some of those space stations get destroyed in wars and conflicts, 

then they will just be rebuilt 

when wars are about to break out, people will temporary be evacuated to space stations and drones will fight the wars 

if territories on earth become irradiated zones because of nuclear wars, 

then people will visit those places with remote controlled drones or in person in protective mechanized equipment 

and when radiation has been reduced, cities will be rebuilt
