3. 2. Dismantling the Conflict Trap : Essays on Civil War Resolution and Relapse

   Författare :Joakim Kreutz; Magnus Öberg; Mats Hammarström; Halvard Buhaug; Barbara F. Walter; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; civil war; conflict resolution; conflict recurrence; diversionary war; ripe moment; natural resources; peace agreement; victory; war termination; Peace and Conflict Research; Freds- och konfliktforskning;

   Sammanfattning : Countries that have experienced civil war suffer a greater risk for new conflict than countries with no prior history of civil war. This empirical finding has been called a conflict trap where the legacy of previous war - unsolved issues, indecisive outcomes, and destruction – leads to renewed fighting. LÄS MER
