Humanitarian intervention

Humanitarian Intervention has been defined as a state's use of "military force (publicly stated that its use is for ending the violation of human rights) against another state." This definition may be too narrow as it precludes non-military forms of intervention such as humanitarian aid and international sanctions. On this broader understanding, "Humanitarian intervention should be understood to encompass… non-forcible methods, namely intervention undertaken without military force to alleviate mass human suffering within sovereign borders."

There is no one standard or legal definition of humanitarian intervention; the field of analysis (such as law, ethics or politics) often influences the definition that is chosen. Differences in definition include variations in whether humanitarian intervention is limited to instances where there is an absence of consent from the host state; whether humanitarian intervention is limited to punishment actions; and whether humanitarian intervention is limited to cases where there has been explicit UN Security Council authorization for action. There is, however, a general consensus on some of its essential characteristics:

The customary international law concept of humanitarian intervention dates back to Hugo Grotius and the European politics in the 17th century. The subject of humanitarian intervention has remained a compelling foreign policy issue, especially since NATO's intervention in Kosovo in 1999, as it highlights the tension between the principle of state sovereignty – a defining pillar of the UN system and international law – and evolving international norms related to human rights and the use of force. Moreover, it has sparked normative and empirical debates over its legality, the ethics of using military force to respond to human rights violations, when it should occur, who should intervene, and whether it is effective.

To its proponents, it marks imperative action in the face of human rights abuses, over the rights of state sovereignty, while to its detractors it is often viewed as a pretext for military intervention often devoid of legal sanction, selectively deployed and achieving only ambiguous ends. Its frequent use following the end of the Cold War suggested to many that a new norm of military humanitarian intervention was emerging in international politics, although some now argue that the 9/11 terrorist attacks and the US "war on terror" have brought the era of humanitarian intervention to an end. James Pattison, however, argued in 2011 that the NATO intervention in Libya breaks this trend.
