How long is the Korean War?

As an expert in military history, I can provide a comprehensive overview of the Korean War, which was a significant conflict in the early years of the Cold War. The Korean War, also known as the "Forgotten War," began on June 25, 1950, and ended with the signing of the Korean Armistice Agreement on July 27, 1953. The war lasted for a little over three years, with the primary combatants being North Korea, supported by China and the Soviet Union, against South Korea, which was backed by the United States and other members of the United Nations. The conflict was a result of the division of the Korean Peninsula into two separate states after World War II, with the North being communist and the South being capitalist. The North Korean invasion of South Korea was an attempt to reunify the country under a communist government. The United Nations (UN), led by the United States, intervened in defense of South Korea, marking the first major armed action requiring a collective response under the UN's auspices. General Douglas MacArthur, appointed by President Harry S. Truman as the commander-in-chief of the U.S. Forces, Far East, and later as the Supreme Commander of the Allied Powers in the Pacific during World War II, played a pivotal role in the war. MacArthur's leadership was marked by a series of strategic decisions, including the Inchon Landing, which was a successful amphibious invasion that turned the tide of the war in favor of the UN forces. However, the war was not without its controversies. The Chinese intervention in October 1950 on behalf of North Korea was a significant turning point, leading to a protracted conflict that saw the front lines stabilize around the 38th parallel. The Korean Armistice Agreement, which was signed in 1953, did not result in a formal peace treaty, and technically, North and South Korea are still at war to this day, as the armistice is not a permanent peace agreement. The casualties of the war were substantial, with estimates ranging from 2.5 to 3 million people killed, including combatants and civilians. The war also had a profound impact on the geopolitical landscape, further solidifying the Cold War tensions between the East and the West. In conclusion, the Korean War was a complex and devastating conflict that had far-reaching effects on the region and the world. It was a testing ground for the newly formed UN and a precursor to the larger ideological struggles of the Cold War era. The war's legacy is still felt today, with the Korean Peninsula remaining divided and the prospects for reunification uncertain.

Truman appointed General Douglas MacArthur, the commander-in-chief of U.S. Forces, Far East, to head the UNC. The Korean War lasted for over three years.
