Peace and Conflict is a biennial publication that provides key data and documents trends in national and international conflicts ranging from isolated acts of terrorism to internal civil strife to full-fledged intercountry war. A major trend it tracks is the incidence of wars beyond the protracted conflicts in Iraq and Afghanistan.
