These include the effects of the conflict on everyday aspects of life, social identity, and mental health.Ethno-political conflict is now considered one of the most important threats to global security (Large, 1997;Mccgwire, 2002). Violent inter-group conflict represents a difficult and intractable problem in many regions of the world. Over the final decades of the 20th Century intra-state conflict (rather than inter-state conflict or war) became an increasingly common problem. The United Nations Development Programme recorded only three wars between states in the period between 1989 and 1992, while documenting 79 instances of intra-state conflicts over the same period, many of which had been underway for a decade or more (Large, 1997).These types of conflicts differ from traditional warfare in a number of ways. The costs of such conflicts tend to be borne by civilians, rather than military personnel. In World War I, 10% of all fatalities were civilians.
