I had to live through four different regimes with Sihankouk, Lon Nol, Pol Pot, and a short time with current government. Good leadership leads to prosperity and happiness. Poor leadership leads to suffering and deaths. Khmer history was very sad and painful one especially during Communist Pol Pot. Can't blame other countries for what happened in Cambodia. Sihanouk always declared Cambodia as a Neutral Country but behind the door, he always sided with communist China, Communitst Vietnam, and Soviet Union then and caused the Vietnam War spilled over Cambodia. I was in my high school year in 1969 and Sihanouk was overthrown by General Lon Nol and the civil war started. I don't think they teach this to the Khmer people now. Khmer politics can be deadly from killing each others for hunger power since Post-Angkorean periods. United we stand, divided we fall. Hopefully the younger generations learn from this and the Khmer history will not repeat itself!
