After World War II, the world was formed into two different systems: capitalism and socialism, leading to a new form of war - "Cold War". Although being called "Cold War," it was manifested by "Hot Wars" such as those in Indochina and the Korean peninsula. The Korean War (1950-1953) and the Vietnam War (1954-1975) were convergence points of confrontation between the two systems. While both of the wars were partly an East-West conflict, they were also a "North-South" conflict. This paper examines a reference by comparing the Korean War and the Vietnam War from a perspective of the Cold War system. Due to developing differently in the international, regional, and national contexts, the Korean War and the Vietnam War differed in various dimensions. The article proposes the similarities and dissimilarities between the two wars and how they still influence present historical issues.
