During eight war months, the effects are perverse, not only the violation of the humanitarian international law, but also the human rights. Within the framework of our work, we try to demonstrate that the main principles of the humanitarian international law were not respected. The attacks of belligerent parties including the foreign strengths were not within the limits of means of fight in particular the use of a tank T-55 in Benghazi and in other cities of the country. As for the method of fight, the hostilities took place during the late hours which talked of massive destructions without saving hospitals and schools, also most victims are civil persons. It is impossible to stop or better to forbid the belligerent parties to wage war because of the conflicting human nature, but the regulations or the mitigation of the latter are possible through the notion of the humanitarian international law, in other words law of war. It is a right to wage war for a just cause by observing certain regulations such as the principle of the right humanitarian worker which stipulates that the respect for the human person and its blooming will be assured in all the compatible measure with the law and order in wartime with the military requirements.

We are going to analyze at first the challenges since his entry in the independence then to demonstrate how they established a brake for the maturity of the RDC and finally we are going to glimpse the ways of exit.
