The year 2013 went out in another blaze of atrocities, bombs, violence and bloodshed. South Sudan, the world's newest country,was merely the latest to erupt in murderous mayhem, joining a long list of unsafe places to be.

It is time surely, well beyond time, to take some action to save the world. I have a modest suggestion to make to try to keep world leaders up to the mark and improve the performance of global governance.

Ban Ki-moon commanded the full weight and power of his office as secretary general of the United Nations to demand that leaders in South Sudan behave themselves, end hostilities and cease the killing of civilians.
