Viet Nam did not win the war. It was not a war between Viet Nam and the USA.The Communists won the war in Viet Nam that was fought when NORTH Viet Nam invaded and ultimately conquered SOUTH Viet Nam. I have met and conversed with old soldiers from the NVA and FLN who believe that Viet Nam, in fact, lost the war- to the Communists. The people of Viet Nam, the ones I met from both sides of that war, hold NO grudges against Americans because they see America as having been helping at least some Vietnamese and as not desiring to colonise or rule Viet Nam. The Chinese are the comparison.
I agree with your clarification.
