With the greatest respect, not quite true. Since 1964 the Shan State Army has been fighting against (and still does) General Win's Junta Tatmadaw. The Burmese Junta now fear democratic support for the civilian Burmese NLD (National League for Democracy) Party formerly lead by Aung San Suu Kyi (now in prison), whose current members live in exile, now the National Unity Government, outside Burma. They are negotiating with "friendly" countries to re-establish democracy - sadly, a hard task, but one lives in hope. The NUG supports the Shan Army and other ethnic groups fighting against the Tatmadaw. Without Thailand, the only support comes from China which is plundering natural resources.
Of interest:
The Burnese Ambassador to tne UN is still a former NLD member and votes against his own country in defiance of the Junta - brave man!
Kyaw Moe Tun was appointed ........ months before the military overthrew the elected civilian government.................. The military junta tried to fire him from his post, but he refused to leave, and so far, the United Nations General Assembly Credentials Committee has refused to recognize the military's appointee. He is also backed by Myanmar's National Unity Government (NUG), .........................
