Humanitarian intervention after the Cold War has been one of the main debates in international relations theories. The term intervention generally brings a negative connotation because it defines as the coercive interference of external parties in a sovereign state belonging to the community. Humanitarian intervention by international institutions and individual sovereign states has often been linked to the use of military force. This is why intervention is often seen as a way to prevent sovereign states from committing human rights violations against their populations. This essay will focus on key concepts enabling humanitarian intervention, primarily regarding morality and justice in international society. This essay will also provide some arguments against humanitarian intervention from different aspects of theories of international relations theory. The question of human rights only appeared in the post-Cold War era, where it was addressed by an international institution, the UN. The preamble of the United Nations states that human rights are afforded to all human beings and that equality exists for all. There will be no sovereign state to prevent its people from exercising these rights. The globalization of capitalism after the Cold War makes the issue of human rights admirable, while it has seen suffering in other parts of the world. Indeed, Western states are considered to be the champions of democracy and therefore constitute an ideal body to carry out activities in favor of human rights. Such human suffering occurs in a sovereign state. A humanitarian intervention led by an international institution will be carried out to end the threat.
