People get the VN War all wrong. We weren't fighting the Vietnamese, we were fighting communist scum, armed by Russia, in order to liberate the Vietnamese. VN was originally 'ceded' to the Japanese during WW2. Hitler kinda talked the French into it.

After WW2, North VN was awarded to the Soviets and became the #1, Numero Uno, Number One destination for Japanese War Criminals who didn't want to commit Seppuku.
Viet Nam is currently slightly better than an open sewer. Poor. Not utterly poor but a shithole, nonetheless. commies can't get anything right.
This is after over 50 years of Independence. On their own. Not only that -- The place is FILTHY. The Air Pollution is stifling, the sewers in most places are more like wishful thinking, drinking the water is taking your life in your hands, Air Conditioning is for the well-off and the food is life-threatening, Traffic is incredible and all the people can drive is 50cc and under motor bikes (about 6 or 7 horsepower). Unless you're well-off.
They're getting better. The VN people are hard-working, industrious folks but they can only do so much with the idiotic form of goobermint they use -- communism.
Contrast that to the South Koreans. Fifty years after their liberation, their Independence... Back in 2003, they had become a world class power. Industrial might, Military might, their culture and their society are First World now.
Compare that to the dimocrap scum-run North Korea. And, yes Virginia. dimocrap scum ARE communists. They're just too gutless, too cowardly to admit it.
