It has become an undeniable reality that the active involvement of children in armed conflict is an endemic problem affecting the countries of the Republic of Congo and the Democratic Republic of Congo (DRC). The participation of children has been condemned by the United Nations Organisation, the International Committee of the Red Cross (ICRC), international human rights Non-Governmental Organisations (NGOs), and the international media, because of the human rights violations involved and war crimes perpetrated. Rational choice theories and interactionist paradigm can be used to analyse the logic of the forced recruitment of children in the two Congos. The war barons, the leaders of the politico-military groups and some of the chiefs of the national armies underestimate the phenomenon of the participation of children in armed conflict, which is on the rise with the re-emergence of fighting in the Eastern part of the Democratic Republic of Congo. While the recruitment of child soldiers is nothing new, the role of children in combat has evolved considerably over the past two decades. This evolution has brought about profound changes in the way these children are perceived and used; from being seen as civil victims of the conflicts to being seen as child soldiers -concomitantly victims and perpetrators.The history of the two Congos, which have been beset over a long period with sporadic fighting, seems to have entered into a cycle of simmering conflicts and all-out war having civil, regional, ethnic, socio-political, and economic dimensions. The armies would be, without the forced recruitment of children, too thinly spread to continue these conflicts. The child soldier has therefore become a principal actor in the region. How can we evaluate and understand this fundamental evolution of the Congo conflicts? What solutions can be envisaged to this phenomenon? What can be done to prevent it? Which counter-measures can be undertaken?Real commitment from the national and international political leaders in the Disarmament, Demobilisation and Reintegration (DDR) process of the United Nations and the European Union, as well as quick and efficient concerted action from the international community is required to prevent the continued enrolment of children, and to obtain the demobilisation of those who served in the armies and the armed groups in both countries. This involves lobbying the army chiefs and the war barons, for whom the prospects of being arrested and appearing before the International Criminal Court, and the consequences of subsequent sentencing constitute a real threat.
