Previously was one single country but was later divided by USA and Russia in 1945 following Japanese surrender. What are these two countries

Answer 1

The country you are referring to is Korea, which was divided into two separate nations: North Korea and South Korea. This division occurred following the end of World War II and the surrender of Japan in 1945. The Korean Peninsula was split along the 38th parallel, with the Soviet Union occupying the northern part and the United States controlling the southern part. This division eventually led to the establishment of two distinct governments and, subsequently, the Korean War in the early 1950s.
