I only brought it up because Mace attempted to pass his own friend's father's opinion of as evidence to show how flimsy anecdotal evidence is.The North Vietnamese won the war because they have the means and support from both China and Russia. The USA supported the corrupt and inept South Vietnamese government and ARVN troops that didn't have what it takes to win the hearts and minds of the majority of the Vietnamese people to join them in their cause. As a result the war became a terrible war of attrition for the US and their South Vietnamese government ally. Your father's friend's opinion about the Vietnam war does NOT equate to history.
I am well aware of the circumstances surrounding the Vietnam War and I have made it clear thought out the discussion if it can be called one.
