Mountain range near Viengxay

Among this hills there were hidden the caves and the sanctuary from the Pathet Lao and its leader Khaysone Phomvihane.
The Pathet Lao are still the only party in this one party communist state. Communism is into its fourth decade and the Lao PDR on to its fifth president but the people seem very contented with their one party state. Maybe communism can work? My view is altered after actually visiting one of the five communist countries left in the world (Vietnam, China, Cuba and North Korea are the others) rather than listening to the western biased propaganda in the media.
