Use of force: defense of the law as challenges to peace and dispute resolution at the international level

Abstract: The present work makes a historical backup of the use of force from the birth of the United Nations up to the present day. It is an important right for the evolution of international law but also for the resolution of disputes in the international context, where the use of armed force even unilaterally, as self-defense, as authorization issued or not by the Security Council now, follows other paths different from those of the past. The maintenance of peace and international security is a very difficult matter now due to the paralysis of the Security Council but also for political, geopolitical and historical reasons. The latter put in evidence the coordination of states, as a coalition not to follow the path of use of force as happened in the past but as a coalition of states, of institutions where wars now are addressed in a different. However, the resolution of disputes continues to remain open and human lives trampled upon. The use of force continues to be the protagonist of the right of the strong, of the winners, of those who, after the wars, influences the global economic environment.
