I asked a Vietnamese friend whose grandparents had been interned in one of the mentioned camps why the South had lost the war. He explained that the soldiers from South Vietnam had shown a suprising level of cowardice and nepotism.

There is perhaps another story, that of a soldier fleeing with expensive military equipment in the moddle of a battle, I bet he is laughing at his collegues who died fighting for their country. In this way it is a microcosm for everything wrong with South Vietnam.
