the population of the earth is around 4 billion as most several trillion people have moved off the planet as the technology became more stable. war has always plaged the planet earth but now the world is in peril of being destroyed by weapons more powerful that any atomic weapon. the 4th world war has been raging for around 20 years. most of the people on the planet have sided with either the nation of Russia or with the American empire. we would be from the American empire and have killed the Russian leader. Russia controls all land east of Germany and America controls all land west of Germany.

just the rough idea i have.
