What I'm saying is, that in the current situation the political significance of the name is more important than whatever the British decided to call it. And accepted English politic-geographic names do change (e.g., Bombay is now Mumbai in English, Persia became Iran (the name that Iranis themselves use)). It's all okay with me, but you are right to consider the political significance of names.

The name by which the country should be called should be left to the people of the country. The opposition to the name Myanmar within Burma and outside of it has come mostly from politicized people who oppose the governments of the past few decades, who renamed it Myanmar. I'm not sure how much this is an issue for those people today, but I'll be happy with whatever the people decide.
Foreign names for countries, including English names them, often have odd origins and this is rarely a real issue for anyone concerned, but in the Myanmar/Burma situation they have taken on political significance. I usually call the place Burma, because I really think that, in the last 52 years at least, the government has been little short of horrible. If you say that 'Burma' is the preferred term for the country among its inhabitants today you may well be right, but I really don't know.

@HFCampo: Your description of smoking/nicotine addiction is ok but most smokers do not continually need to smoke more & more - I don't smoke any more now than I did decades ago.
Also, I don't understand why this is stealing from one's family.
I agree with you that nicotine addiction is a problem, and that this legal drug (nicotine) does more damage than some (not all) of the illegal drugs that you are so against.

Seems to me that, if, as you say, we cannot define which drugs should be illegal and which illegal, as the governments that you don't respect have all the power in this regard, it would also be the case that we have no power to oppose drugs like nicotine that are legal.
So - there are problems with drugs, both legal and illegal. What to do?

Introduction to the article: the CEF troops were not PRC government military forces operating outside the PRC's borders because the PRC did not then exist. Neither was the CEF a Communist Party unit, though there may have been a few individual communist troops within it.

On translation 'Burmese': the clearest way to distinguish ethnicity in the country once called Burma is to use the word 'Burmese' to refer to all citizens of Burma; the majority ethnic group in Burma are best called Burmans. Other ethnic groups are Karen, Kachin, Shan, etc.
