One of the few differences between korea and vietnam was the outcome of the conflicts. contrast the outcome of the two conflicts.

1) Vietnam war was officially ended whereas Korean War ended in a Cease-Fire which means it never ended in official way

2) Korea was a short war and Vietnam was a Long war

3) Korea was like WW2 Whereas Vietnam was similar to Guerilla War

Hope this helps!
