My new theory is that some unpaid intern from "Privacy International" actually colored this map for their boss, and they did it in MS Paint, and there was a pixel-or-two gap in the border of Vietnam so when they filled the oceans white it filled in 'Nam too. Their
website certainly proves there are no graphics gurus working over there. I'm betting the guy who did
last year's map (which does have Vietnam) isn't there anymore.
