By the end of World War I, many changes took place in both Europe and Asia.
While much of the map of Central and Eastern Europe was redrawn, Asia was also significantly weakened, which eventually lead to the problems experienced in World War II.
Eastern Europe was in Chaos with many new nations being formed, many weak, with several internal factions becoming powerful and challenging the government.
The Central Government in China was also very weak which led to rebels and Mao forces becoming more powerful. On the other hand, a weakened China also became vulnerable to attacks from Japan.
