Politically the war goes on and still they lost the war back in the 1980s. They pay lip service to socialism these days, but they have to survive in a Free Enterprise world. When it was just the French or the Americans they were fighting, they could use guerrilla warfare, much the same warfare Americans used to defeat the British. And they successfully defeated the enemy that way. But killing Free Enterprise is a different matter.
Today there is a Vietnamese stock exchange.
It has only four stocks for now, but its mere existence indicates who won the war politically. There are nearly 80,000,000 people in Vietnam and about half were born after the war. The young people want prosperity, money, careers. The Communist Party finds itself outnumbered and in trouble. The symbols that inspired people during the war do not convince the young that Socialism is noble.
