Vietnam War and Korean War ended differently because Vietnam was united, while Korea remained divided.
In fact, Vietnam War ended in 1975 with a communist North Vietnam's victory in which this country annexed South Vietnam, a Pro-American capitalist nation, and re-united the territory under a communist government.
On the other hand, the Korean War, that also faced communist against capitalist factions (North Korea and South Korea respectively) ended in 1953 with an armistice in which both sides remained divided, keeping their territories with minimal territorial changes.
