A few points
1) Viet Nam, while comparatively well run, is a Communist Dictatorship.
2) In my experience,almost all Vietnamese, even those who have spent years in reeducation camps are loyal to Viet Nam. This is especially true as their is a significant, though relatively small, chance that Viet Nam will be at War in the not too distant future.
3) The Vietnamese spending on defense over the last 10 years has skyrocketed because their is a significant, though relatively small, chance that Viet Nam will be at War in the not too distant future.
4) In Vietnamese eyes, China is the aggressor and mortal danger.
5) Viet Nam, America, Australia, Japan, Israel and a number of other countries are moving closer to an unofficial Alliance and are materially assisting and supporting the Viet Nam defense build up.
6) The Bà tâm or Old Ladies Security Network is an integral part of the local and National security networks and should be respected.
My wife and I have always taken the time to have a friendly chat with any of the
“old ladies” that wished to chat with us. We have answered their many questions with complete openness, honesty and respect for their responsibilities. One thing that you give up for the privilege of living in Viet Nam is any right to privacy. The Vietnamese don't have that privilege and neither do we as long as we choose to live here.
In truth, thanks to the internet on privacy; “That horse done kicked open the barn door, jumped the fence, took off running down the road and is now plumb out of state.” World wide, for good or evil, privacy is pretty well a historical and dead issue. Understandably foreigners do get more attention than the Vietnamese. Most of that is likely because, they have a lot less information about us and need to fill in the blanks that were filled in on the Vietnamese years ago.
Note, I have two years Police experience, mostly as a “Traffic Cop” on a US Military Base in Japan. During that time, between USAFI(United States Armed Forces Institute)and Los Angles City College Overseas, I earned roughly 30 semesters of college credit in “Administration of Justice.” While I have no military training or experience in Intelligence except for a brief lecture in “Boot Camp.” I am interested in the subject, have studied it and have talked to friends that have been involved in Intelligence.
