The history of the war is plainly relevant to Vietnam's economy today. At the very least it is crucial to supporting the article's thesis that capitalism is providing an incentive and engine for the suppression of this historical memory.
Unfortunate to see Vietnam turning into a new China.
Framing the Vietnam war as a communist struggle against Western invaders is naive and incorrect. South Vietnam was governed by a nationalist but anti-communist government that sought aid from the US and others, while North Vietnam was a communist government that was aided by the USSR and China.
First google hit.
As far as invaders go, both sides invited so many vistors and advisors its hard to say who that is.
As you can see, most of these divisions were short-lived and that idea that Vietnam was one unified country for a long period of time before being arbitrarily split by warring politicians is not correct.
It's well on it's way to becoming South Korea.
Tho' they don't hide their political bias, and it is often interesting reading same news stories in the Guardian (left leaning UK paper) vs lets say the Telegraph (right leaning UK paper) for differing view points and then making up ones own mind.
That said, the facts and stories presented in the article are themselves interesting and enlightening.
