Not having read further, so not knowing what was written, I can relate my own experiences in the late eighties, on this matter.
Back then I worked at the Pentagon with a close friend, a senior Marine officer, who was trying to help the families of the POW’s. From him, I heard the stories, at the time, hugely politically incorrect, about 312 POW’s known to be left behind and alive and in a camp. He understood the lives of these had been negotiated away at the bargaining table by Kissinger, but was trying to break through the barriers to get some sunlight on the issue.
But it was not to be. Every step of the way, he was thwarted by an unseen hand at times and by one in a key position to smother any such rebellion, Richard Armitage. Sound familiar?? As I recall either he or another friend also thought the same was operating out of the embassy in Thailand earlier and was blocking investigations back then.
I guess sources available now could confirm or deny the accuracy of these stories.
My friend who is a faithful and practicing Christian and fine family man was finally just shoved aside, left the Pentagon, and that was that.
I just renewed my faded POW flag. The black bleaches out fairly quickly in the weather. God bless and help those poor souls.
