Yeah, as a Vietnamese, this title definitely feels offensive to me. Maybe this article is written with American audience in mind. In Vietnam we call the war American war btw. Depends on where you are from, the title could have used the term "USA of programming" :)
Why did it not age well? Are there any new findings regarding Vietnam?
To most people in the world, "Vietnam" is not a war, and is not merely a symbol of absurdly misconceived incompetence.
