What is going on in Korea?

Truce talks began in July 1951, but the fighting continued until July 1953, when the negotiations at last bore fruit and the conflict ended in a cease-fire agreement.
Unlike after its previous wars, the United States did not fully and immediately demobilize after the fighting subsided in Korea. Production and spending continued at a relatively high level. In this respect, the Korean War was the most important event in the history of the Cold War, and, indeed, was a watershed in American military history. After this war, the United States embarked on the first long-term peacetime program of military and industrial preparedness. No longer would the country virtually disarm after a war; instead, it would promote the concept of readiness. No longer was the question whether or not to produce, but what to produce and how much.
In comparison to the naval forces engaged in World War II, Korea was a small war. At no time were more than four large carriers in action at the same time. Yet in the 3 years of war, Navy and Marine aircraft flew 276,000 combat sorties, dropped 177,000 tons of bombs and expended 272,000 rockets. This was within 7,000 sorties of their World War II totals in all theaters and bettered the bomb tonnage by 74,000 tons, and the number of rockets by 60,000.
