Except the war in Vietnam was fundamentally different to that in North Korea. It was a direct outcome of the French colonial war in the early 50s which the US decided to support for semi-absurd reasons ("domino theory"). Geopolitically China was always a much bigger threat to Vietnam than anyone else so had the US made the right choices in the 40s and 50s it would've been easy to turn it into a state which was friendly or at least neutral towards the US (like Yugoslavia for instance).
