If it's any solace, We won the primary goal of the Vietnam war. Soviet support of North Vietnam combined with the later efforts in Afghanistan bankrupted the country and caused the collapse of the Soviet bloc- which stayed collapsed until Barry O'bama breathed life back into it. The secondary goal was to prevent South Vietnam from falling to North Vietnam. This too was accomplished in that the various NVA invasions had disastrous results for NVN, resulting in changes of command and finally a treaty in 1973 where NVN promised to cease further aggression- at that time, following the disastrous Easter offensive, they couldn't have attacked a high school football team. but it gave an out for the US to officially withdraw. Then two years later, the NVA rebuilt, they attacked and finally succeeded in overrunning SVN. But look at VN now- it is Communist in name only- it has little relationship with China and it is moving as fast as possible to a market economy. Prior to recent Soviet and Chinese actions, the Vietnam war was the highwater mark for worldwide Communism- the 58,000 that died stopped the greatest threat to freedom since the Third Reich.
