I was wondering why there are two Koreas. I looked it up. It looks like Japan's annexation of Korea in 1910 was a bad idea. This should be one country. That might eventually happen but not for a very long time.

In 1910, Korea was annexed by the Empire of Japan. After the Japanese surrender at the end of World War II in 1945, Korea was divided into two zones, with the north occupied by the Soviets and the south occupied by the Americans. Negotiations on reunification failed, and in 1948, separate governments were formed: the socialist Democratic People's Republic of Korea in the north, and the capitalist Republic of Korea in the south. An invasion initiated by North Korea led to the Korean War (1950–1953). The Korean Armistice Agreement brought about a ceasefire, but no peace treaty was signed.^[15]K
