Re Burns' Vietnam series, from DelVecchio's Burning History: Deceptions and A Teaspoon of Sand:
“Reunite what country?” Recall, Indo-China was not one country, or even three countries, under the French. It was administered as six regions (Laos, Cambodia, Tonkin, Annam, Cochin China and the Crown Dominion Lands). Vietnam was not one country before the French. In the previous millennium it was united for perhaps 30 years. Most of this unification refers to unifying the area north of the Red River with that of the area south of the Red River—all of that territory being within what became known as North Vietnam. It does not refer to the area from the border with China in the north to the tip of the Ca Mau peninsula in the south or west to the mountain border areas with Cambodia and Laos. That had never been one country. There was nothing to reunify. This is not analogous to the American Civil War. This was not a nation that was split by colonialism, by war or by agreement.
