The military junta in Burma controls a disciplined army of youths brainwashed since they were inducted into the army at very young ages. So there is little chance of a military coup. The regime is happy to keep its people poor in order to maintain its iron grip and exploit the country's mineral wealth for the benefit of the military leaders.
What crimes will the military have to commit that would shock the UN enough for it to encourage an invasion of Burma? A programme of mass extermination based on ethnic identity?
The UN is only a talking shop. Why Ireland puts so much faith in it is beyond me. It's only useful as a symbol of international cooperation. The Democracies should form their own UN.
