Ethnic conflicts that lead to civil wars or other forms of internal turmoil elicit myriad forms of military intervention from the global community. Sometimes the United Nations decides to deploy peacekeeping troops to a region or authorize individual states to use their military resources to quell a conflict. Usually, a state will unilaterally decide to launch an intervention before the United Nations makes a decision, a situation that generally occurs when the state has a direct interest in the conflict. Although many external factors play into these decisions regarding intervention, four internal factors have been identified as having a strong influence on these decisions: the failed state status of the region in conflict, the duration of the conflict, a request for external help, and whether a major world power is already involved. The United Nations is more likely to intervene in a critically failed state whose ethnic conflict has been enduring for years, where a state will send its military in unilaterally if the conflict is new (months old) and a request for military help is made from one of the parties already involved.
