Oh, I assumed the museum would be more about the Khmer Rouge. In fact Wikipedia says

> The landmines in Cambodia were placed by different governments and factions (including the Lon Nol, Khmer Rouge, the Heng Samrin and Hun Sen regimes, as well as the Coalition Government of Democratic Kampuchea who, with international support retained the UN seat throughout much of the 1980s) that clashed during the Civil War in Cambodia in the 1970s and 1980s

So it's not clear to me that has anything to do with the US presence in Vietnam.

I believe you are correct about the Khmer Rouge period being the source of the bulk of the Cambodian problem, however the museum's collection was quite comprehensive. It's been too long since I visited (and it seems they have since been forced to relocate) for me to be certain of what if any of the collection covers US secret war period, but I'm certain that I saw American made mines in their collection.

My visit to this museum sticks with me to this day, and my desire to promote it is perhaps out of place on this specific topic.

I stand by all of my other links as being directly relevant.
