Humanitarian intervention

Humanitarian intervention is the use or threat of military force by a state (or states) across borders with the intent of ending severe and widespread human rights violations in a state which has not given permission for the use of force. Humanitarian interventions are aimed at ending human rights violations of individuals other than the citizens of the intervening state. Attempts to establish institutions and political systems to achieve positive outcomes in the medium- to long-run, such as peacekeeping, peace-building and development aid, do not fall under this definition of a humanitarian intervention.

There is not one standard or legal definition of humanitarian intervention. Nonetheless, there is a general consensus on some of its essential characteristics:

Humanitarian intervention involves the threat and use of military forces as a central feature.

It is an intervention in the sense that it entails interfering in the internal affairs of a state by sending military forces into the territory or airspace of a sovereign state that has not committed an act of aggression against another state.

The intervention is in response to situations that do not necessarily pose direct threats to states' strategic interests, but instead is motivated by humanitarian objectives.

The customary international law concept of humanitarian intervention dates back to Hugo Grotius and the European politics in the 17th century. However, that customary law has been superseded by the UN Charter, which prohibits the use of force in international relations, subject to two exhaustive exceptions: UN Security Council action taken under Chapter VII, and self-defence against an armed attack. The type and frequency of humanitarian interventions have changed drastically since the 19th century, with a massive increase in humanitarian interventions since the end of the Cold War.
