In the Korean War, North Korea did not claim sovereignty over the entire Korean peninsula, and the conflict ended in a stalemate with an armistice signed in 1953.
North Korea claiming sovereignty of the entire Korean peninsula was NOT true about the Korean War. In reality, the Korean War was a conflict primarily between North Korea (allied with China and the Soviet Union) and South Korea (backed by the United Nations, primarily led by the United States). The war ended in a stalemate with an armistice signed in 1953, not a peace treaty.
