Wait a second, you think 600 peasants a DAY for 10 years wouldn't have won the war?

600 peasants A DAY represents 219000 a year.
This is over TWO MILLION people in 10 years.
we assume 20 births per 1000 people, and you are talking about 800000 people born a year.
So, you only have a growth of at best 600000 people a year. This isn't counting in the death rate. 240000 more people a year die at a 6 in 1000 rate. This puts them to a growth of ~350000 a year. For their entire nation. This is assuming only 600 peasants a day.
Those same losses on us would have been a pathetic joke, not absorbing a full HALF of our population growth. Yes, we'd have eventually "won" vietnam if we stayed in there, but Unlike Iraq and Afghanistan, there would have been no gain to such a victory. Vietnam wasn't a horrid dictatorship country whom was defying international law and thumbing their nose at no fly zones, while abusing programs that were supposed to be for the benefit of their people but only went to buy weapons and luxuries for the elite.
Vietnam also wasn't harboring training camps for individuals to launch attacks at the mainland of the continental United states.
Insurgencies aren't as hard to defeat as you think they are. Defeating an insurgency is no different than defeating a rebellion. They do take a mandate of the population who is supporting the effort to defeat it though. There is no honor or glory in defeating an insurgency, so it is generally difficult for people to stomach the day in, day out efforts and casualties required.
