As the military regime in Burma attempts to suppress the protest marchers, they are in the process of attempting to isolate Burma from the rest of the world, presumably so they can use methods they would prefer to keep from concerned eyes. Bear in mind that the diminished signs of protest we are seeing on our tv screens are largely images from Rangoon and that other cities remain very active, chief among them being Mandalay, the heart of the Buddhist monasteries.
Here in Canada, I've noticed that the national broadcaster (the CBC) is increasingly using the "Burma" to refer to the country the military dictatorship call Myanmar. "Burma" is becoming a symbol for what the democratically-elected party and its supporters are risking their lives for and Myanmar the imposed regime. The Internet has played a significant role in getting the images of the demonstrations to the world. It can also give us a way of taking the pulse of changing views outside Burma. To find a measure of the use of these two charged terms, I went to Google Trends. Not much difference yet overall but of the top 10 countries, Sweden and Denmark are the only two preferring "Burma". And eight of the top ten cities listed (those outside Asia) prefer "Burma". My prediction is that the trend to the use of Burma will grow significantly.
A search on Wikipedia for "Burma" redirects you to the page for Myanmar. I guess they have to stay with government terminology.
Rather than leave a quickly-dating news video, here's a recent, brief appeal from Canadian Jim Carrey for support for the democratic forces in Burma and their leader Aung San Suu Kyi. [updated, with Chinese subtitles, October 5, 2007]
UPDATE - October 14: From a blog post by George Monbiot:
The businesses still working in Burma are having to scrape the barrel of excuses. Even Tony Blair, that bundle of corporate interests in human form, said “we do not believe that trade is appropriate when the regime continues to suppress the basic human rights of its people.” Explaining his company’s decision to pull out of the country, the CEO of Reebok noted that “it’s impossible to conduct business in Burma without supporting this regime. In fact, the junta’s core funding derives from foreign investment and trade.” As the junta either controls or takes a cut from most of the economy, as almost half the tax foreign business generates is used to buy arms, any company working in Burma is helping to oppress its people.
