Ban Ki-moon is said to be angry, or as a diplomat perhaps it's frustration.
Yesterday [Thursday 7th June, 2012] he said "How many more times are we to condemn them, and how many ways must we say that we are outraged?".
However, we are getting a sense here of the United Nations becoming muted!
There is one country Syria, one government, lead by one man and they are [allegedly] killing their own people, and no one is doing anything about it, so it must be all right eh?
