Humanitarian intervention has been defined as a state's use of "military force against another state when the chief publicly declared aim of that military action is ending
human-rights violations being perpetrated by the state against which it is directed." 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:
- 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.
