Korean-Japanese Empire (Reversal)

History
Due some instability in 1901, the Korean Empire signs a pact with the Empire of Japan. All of the Korean peninsula is united with the island of Japan into one country, with the rule of the Korean and Japanese government controlling their territories. In late 1928, the Sino-Soviet Union, decides to try to invade the mega country in an attempt to gain more land, starting the Sino-Korean-Japanese War. With help from powerful allies such as the Brittania and New Vietnam, Korea fends off the Sino-Soviet forces, and even gains some of the land that was once part of China & Russia. Brittainia and the Confederate States both invest millions of dollars into Jap-Korea's economy. The Empire soon desolved after WW1 into 4 seperate nations, Japan, Korea, Astena, and Dilen. After the fall of the Sino-Soviet Union in 1997, Japan and Korea took the places of Russia and China in the council of five, signifying both their place as a world power.
