Further to this post of mine yesterday, see the UN outcome document [pdf]:
138. Each individual State has the responsibility to protect its populations from genocide, war crimes, ethnic cleansing and crimes against humanity. This responsibility entails the prevention of such crimes, including their incitement, through appropriate and necessary means. We accept that responsibility and will act in accordance with it...Bronwen Maddox in The Times:139. The international community, through the United Nations, also has the responsibility to use appropriate diplomatic, humanitarian and other peaceful means, in accordance with Chapter VI and VIII of the Charter, to help protect populations from genocide, war crimes, ethnic cleansing and crimes against humanity. In this context, we are prepared to take collective action, in a timely and decisive manner, through the Security Council, in accordance with the UN Charter, including Chapter VII, on a case by case basis and in cooperation with relevant regional organizations as appropriate, should peaceful means be inadequate and national authorities manifestly failing to protect their populations from genocide, war crimes, ethnic cleansing and crimes against humanity...
That may be the achievement for which this summit comes to be known.UN News Centre:
Responsibility to Protect - unambiguous acceptance by all governments of the collective international responsibility to protect populations from genocide, war crimes, ethnic cleansing and crimes against humanity; willingness to take timely and decisive collective action for this purpose, through the Security Council, when peaceful means prove inadequate and national authorities are manifestly failing to do it.
