So, do you insist on calling Germany - Deutschland, Russia - Rossiya, Finland - Suomi, Albania - Shquiperia, Egypt - Mysr, India - Bharat, etc.?
Touché. Of course not; it was merely to illustrate that it's not entirely ridiculous to decry the use of "Cambodia", although it is inaccurate. I freely admit my error, in any case.
My point on Myanmar stands, though. 
Not really, I don't think the US recognizes the government that made the name change as legitimate. Nor would I, frankly. The "Myanmar" government is pretty darn despicable, and the name is about as arbitrary as Zaire was. The people are 'Burmese' or alternatively whatever the local ethnic group is.
I prefer to call the state 'Burma' (although what I'd call it irrelevant; I would prefer to call Iran 'Parthia', Syria 'Assyria', Iraq 'Mesopotamia', and Pakistan 'The Islamic Republic of West India' but no one would follow my lead. One day, I'll rename half the world the way it SHOULD be.... maybe redraw a few national boundaries too
).
