Résumé:
Non international armed conflicts have become the prominent feature of contemporary armed conflicts, especially in light of the stability of the rule not to resort to the use of force or the threat to use it in international relations, in implementation of the provisions of Article (2/4) of the United Nations Charter. Thus, international armed conflicts have receded, and in the face of growing The challenges posed by non international armed conflicts as a result of their consequences, the United Nations had to address And since the Charter of the United Nations is like a constitution for the international organization, the assessment of the legitimacy of its role in non international armed conflicts is through the provisions of the UN Charter, and since the Charter states as a general rule that the United Nations may not interfere in the internal affairs of states in application of the provisions of Article (2/7) Including the inadmissibility of its intervention in non international armed conflicts. However, this rule is met by an exception that allows the United Nations to internationalize non international armed conflicts in the event that the measures of Chapter seven of the Charter are applied. The internationalization of the United Nations for non-international armed conflicts in this case is through the Security Council resolutions related to the conflict, whereby the Security Council issues a resolution that qualifies the conflict as posing a threat to international peace and security and defines the method of UN intervention, whether through preventive mechanisms Or the remedial mechanisms, relying on his discretion, in application of the provisions of Article (39) ofhe Charter. A Practical practice has shown that the role of the United Nations in the internationalization and settlement of non-international armed conflicts is still lacking in effectiveness without negating the existence of relative effectiveness, which was the result of many obstacles that led to the limitation of the role of the United Nations, especially under the control of the Council Security as an executive body in the means and mechanisms of collective security, which is subject to the control of its permanent member states, those countries that work to direct the Council in a way that serves their interests This explains the selectivity of the United Nations' role in non inrnational armed conflicts, as we find that it has interfered in the 2011 Libyan conflict while it was unable to intervene in the 2011 Syrian conflict due to the right of veto, prompting voices calling for UN reform in order to ensure its effectiveness. In performing its tasks and functions for which it was established.
