The Vietnamese - what a bunch of ungrateful bastards.
Yeah, what difference between one [once through thick and thins brother in arm who, on the advise of the Soviets, turns around and snap at you a couple of snaps] and that of another [through thick and thins who will forever remember and appreciate the sacrifices you had made in the nationhood of their nation] as the below illustrates.

And no! Not all Vietnamese had descended from southern China. Yes, the greater majority of which were persecuted and which were turned into boat people’s probably are mostly of Chinese heritage.
The one’s who call the shots in Hanoi now, aka the Vo Van Giap breed of Vietnam, my opinion, are of Pinoy-Indonesian heritage meaning all three groups are what the Chinese considers as people that are yet [fully developed or yet 100% civilized].
