capacity to deal forcefully with those who would violently disruptive -- and to ensure in particular that there will be no more debacles in the future like Srebrenica in 1995, when 8000 men and boys were taken from under the unprotesting noses of UN peacekeepers and led to their slaughter. The R2P and POC norms are very much sister concepts. They differ in just two respects, neither significant for present purposes. POC is broader than R2P to the extent that the rights and needs of populations caught up in armed conflict go well beyond protection from mass atrocities. But in one major respect the scope of R2P goes well beyond POC, in that it is concerned with preventing and halting mass atrocity crimes regardless of whether they occur in times of armed conflict. Cambodia in the mid-1970s, Rwanda in 1994, Kenya in 2008 and Libya at least at the time of the initial UN intervention in February /March 2011 are major examples of such one-sided violence, non-war situations.
