Finally, I would remind Mr. Henn that the point of the Vietnam war has nothing to do with whether we called the country 'Nam or Vietnam .  It is that today Russian military personnel operate their ships and planes out of our former base complex at Cam Ranh Bay while the political language Ho Chi Minh imported from Moscow is now current through all of Indo-China .
At last, I would mention again to Mr. Henn the goal of the war is irrelevant to what we call the country.
