sendo anulado pelo governo Hindu, sofrendo com boicotes atraves de restricoes rebelioes e conflitos armados com o governo. Com isso pergunta-se: ate aonde o poder e a responsabilidade da ONU em solucionar conflitos mundiais, seja eles internos ou externos, esta sendo usado para soluciona-los, partindo do principio que ela e considerada a forca maior no que tange as relacoes internacionais? Apos anos de atuacao em diversos cenarios mundiais qual seria a verdadeira funcao da ONU? Sera que ela poderia atuar de forma diferenciada em conflitos ou somente apos o termino dos mesmos, atuando como mantenedora da paz dando suporte para civis que praticamente perderam muito com os conflitos. Manter a paz apos conflitos seria essencial para o mundo atual? Ou ja entramos em uma era que a Organizacoes das Nacoes Unidas teriam que ter outra funcao? Talvez a de evitar ao inves da de reparar os danos causados pelos conflitos, concluindo que tal especie de responsabilidade constitui a garantia do cumprimento das disposicoes do acordo firmado entre as nacoes relacionado a paz mundial.Nesse contexto, e intencao deste estudo a analise sobre o papel da ONU em conflitos internos, desenhando suas linhas gerais e ainda alguns aspectos tenues do contexto historico que influenciou e guiou o ao conflito e por fim ao o seu fim. ABSTRACTThe responsibility is much discussion of the UN in resolving conflicts, given that often lacking in some shows, this study will be noted by the conflict in Sri Lanka that lasted almost twenty eight years, resulting in many civilian deaths and exterminating Tamil, a people who already inhabited the territory more than a century and was gradually being aborted by the Hindu government, suffering from boycotts by restrictions rebellions and armed conflicts with the government. Thus the question arises: How far the power and responsibility of the UN in resolving global conflicts, whether internal or external, is being used to solve them, assuming that it is considered a force majeure regarding international relations? After years working in various global scenarios which would be the true function of the UN? Could she act differently in conflicts or only after the end of them, acting as the peacekeeping giving support to civilians who almost lost a lot of conflicts. Keeping the peace after conflict was essential to the world today? Or have we entered an era in which the United Nations organizations would have to have another function? Perhaps to avoid rather than to repair the damage caused by conflicts, concluding that this kind of responsibility is ensuring compliance with the provisions of the agreement signed between nations related to world peace.In this context, it is the intention of this study, analysis on the UN role in internal conflicts, drawing broadly and even some subtle aspects of the historical context that influenced and steered the conflict and finally to its end.PALAVRAS-CHAVE Sri Lanka Conflito Responsabilidade - ONUKEYWORDS Sri Lanka - Conflict - Responsibility UNOuvirLer foneticamenteDicionario - Ver dicionario detalhado1 - INTRODUCAOO objetivo principal da ONU e manter a paz, atraves de intervencoes com tropas que estudam as melhores formas de
