According to New York times world news, there are old U.S. allies, still hiding in Laos. 

Men who say they fought a secret war for the C.I.A., are still on the run with their families in the mountain jungles of Laos. 40 years ago the C.I.A. hired thousands of jungle warriors to fight Communists on the western fringes of the Vietnam War. The men are hunted periodically by a Laotian Communist Government still mistrustful of them for siding with America. One group has been attacked twice this year by the Laotian Army, each resulting in death. In may, they killed a woman and her 2 year old child. In September, soldiers killed a 5 year old boy. This group moves every two weeks to avoid attack. There are still thousands of veterans and their families surviving in the jungle. Many groups have not seen an American since 1975. These people have been struggling in the jungle for over four decades.
