The Times is today reporting the forced repatriation by the Thai army of Hmong refugees from a camp near their border with Laos. The Hmong people fought on the side of the Americans during the Vietnam war. After the fall of Vietnam, some 100 000 Hmong settled in the United States. The role that the ethnic Hmong played in the war against communism is not very well known. [Some of the comments to the Times on-line report leave something to be desired in terms of their attitude to refugees.]
I first came across the story of the Hmong through Clint Eastwood's film Gran Torino.
