On 12 December 2002, the international community celebrated the twenty-fifth anniversary of the opening for signature of 1977 Protocol II Additional to the Geneva Conventions of 12 August 1949, and Relating to the Protection of Victims of Non-International Armed Conflicts. In view of today's armed hostilities around the globe, this anniversary raises the questions whether international humanitarian law provides substantive regulation protecting civilians in non-international armed conflicts; whether such legal protection is effectively countering the sufferings of the civilian population and what are now the main challenges for the international community vis-à-vis internal armed conflicts.

Non-international armed conflicts are more numerous, more brutal and entail more blood-shed today than international ones. The Statute of the International Criminal Court explicitly upholds the traditional distinction between international and non-international conflicts, and armed conflicts will have to be characterized accordingly. But the tendency to adapt the international humanitarian law (IHL) regime for non-international conflicts to the rules for international ones emerges. Article 7 on Crimes Against Humanity and Article 8(2)(c) and (e) on War Crimes amount to real progress in this respect. Yet, the regulation on war crimes in particular does not provide for comprehensive criminal responsibility of individual perpetrators in non-international conflicts.
