The United Nations has been diplomatically trying to persuade Burma leaders for a long time. They tried by sending envoys. They talked with beautiful diplomatic words, but people have already known in advance that they cannot realistically hope for anything before the UN envoys come. The UN could not do anything for Burma. They could not count even death after last September's uprising. Since then we have deeply disappointed by the UN's failure.
The United Nation is likely very afraid of confrontation with China and Russia. Whenever both China and Russia say no, the United Nations was unable to change to say yes. They are always accepting and showing a kind of "obedience" to China and Russia. Were there any severe words or correcting comments made by UN leaders to Burma leaders? They have no authority to change Burma into a nation based on democracy. So the world is very dangerous under the leadership of cowards.
I wonder why most of the world seems content to be merely on-lookers for the Burmese people who are being persecuted. They have no weapons and not like others. They are relatively helpless now. They want to freely survive like you. Even Buddhist monks who stay away from killing are also longing for US, UK and France to enter the country by force. Why? Because they want to see the people with enough food to continue to survive.
You cannot diplomatically persuade Burmese military leaders to give up their kingships. Even the Buddha and the Gods will be unable to preach to them or to guide them. They regard themselves as the best players. They have already decided how to win tomorrow's match. Remember that you cannot win by playing with them without weapons, but only with the help of weapons. What is Ban Ki Moon's suggestion? Isn't it clear that he is just playing a diplomatic game? If so, how many of us have to die for his diplomatic game?
