Korean War

The Korean War (25 June 1950 – 27 July 1953) was a war between the Republic of Korea (supported primarily by the USA, with contributions from allied nations under the aegis of the United Nations) and the Democratic People’s Republic of Korea (supported by the People’s Republic of China, with military and material aid from the Soviet Union). The war was a result of the physical division of Korea by an agreement of the victorious Allies at the conclusion of the Pacific War at the end of World War II. The Korean peninsula was ruled by Japan from 1910 until the end of World War II. Following the surrender of Japan in 1945, American administrators divided the peninsula along the 38th parallel, with United States troops occupying the southern part and Soviet troops occupying the northern part.

The failure to hold free elections throughout the Korean Peninsula in 1948 deepened the division between the two sides; the North established a communist government, while the South established a capitalist one. The 38th parallel increasingly became a political border between the two Korean states. Although reunification negotiations continued in the months preceding the war, tension intensified. Cross-border skirmishes and raids at the 38th Parallel persisted. The situation escalated into open warfare when North Korean forces invaded South Korea on 25 June 1950.[9] It was the first significant armed conflict of the Cold War.[10] In 1950 the Soviet Union boycotted the United Nations security council, in protest at representation of China by the Kuomintang / Republic of China government, which had taken refuge in Taiwan following defeat in the Chinese Civil War. In the absence of a dissenting voice from the Soviet Union, who could have vetoed it, USA and other countries passed a security council resolution authorizing military intervention in Korea.

The United States (88% of foreign troops) and other members of the United Nations force (12% of foreign troops), came to the aid of South Korea in repelling the invasion, but within two months the defenders were pushed back to the Pusan perimeter, a small area in the south of the country, before the North Koreans were stopped. A rapid UN counter-offensive then drove the North Koreans past the 38th Parallel and almost to the Yalu River, and the People’s Republic of China (PRC) entered the war on the side of the North. The Chinese launched a counter-offensive that pushed the United Nations forces back across the 38th Parallel. The Soviet Union materially aided the North Korean and Chinese armies. The active stage of the war ended on 27 July 1953, when the armistice agreement was signed. The agreement restored the border between the Koreas near the 38th Parallel and created the Korean Demilitarized Zone (DMZ), a 2.5-mile (4.0 km) wide buffer zone between the two Koreas. Minor outbreaks of fighting continue to the present day.

With both North and South Korea sponsored by external powers, the Korean War was a proxy war. From a military science perspective, it combined strategies and tactics of World War I and World War II: it began with a mobile campaign of swift infantry attacks followed by air bombing raids, but became a static trench war by July 1951.¹
