The concluding chapter summarizes the five main findings: (1) A divergence between the scale of political compromise and the distribution of military power partly explains why peace collapses. (2) Terminating a civil war through a military victory and ending a conflict through a peace agreement are equally effective for preserving peace. (3) Peace is more unstable after mere ceasefires than after peace agreements. (4) The peacekeeping environment strongly influences whether peacekeeping missions indeed keep the peace. (5) Opportunity for rebellion is not sufficient for civil war to recur, but when more feasibility factors are present, civil war recidivism is more likely. This chapter also discusses policy implications.
