I forgot the name of the man to attribute this quote:
"The Vietnamese are the hardest working people in SE Asia. If it wasn't for the communists, Vietnam would have been the perfect model for pure capitalism. As it is, they are steadily throwing off communism because communism is not their national character."
The Vietnam War (both French and American versions) is the 'cause and effect result' of government intrusion in a military theater of operation. There were too many government suits thinking they were generals and too many generals thinking like government suits. We never lost a battle in Vietnam.
Also because the Hanoi Politburo became extremely jealous of those $$billions in Vietnamese-American remittances to families in the South, and realized that they'd never get a piece of the economic pie until they loosened up on the Marxist rhetoric.
Hanoi has increasingly come to realize that Marxism and Stalinst controls are incompatible with prosperity. So they send their kids now to the University of Sydney or UCLA (believe it or not, a popular form of kickback to Party members), and when the kids return to VN, they are completely cured of Marxist thought.
