Mandated Colonies
When the teritories were stripped from the central powers after WWI, they were partioned out to the people living in the regions as "mandates", which meant that they were "lent" to the people and they were to report back to the allied powers (mainly Britain and France) on their progress. In reality, these teritories became colonies of Britain, France and The United States.

United States
The roaring Twenties
During the duration of the war, the U.S. spent most of it's time selling armaments to the allied powers. When the war ended, the U.S. still had all of it's factories and trained workers to work in those factories. What resulted from this was a period of great economic prosperity known as the "Roaring Twenties".
