In light of modern warfare and modern Catholic teaching, Duffey examines
and assesses three Christian approaches to peace and war. Through
extensive ethical analysis of the Gulf War, he examines the role of the
churches to avert war, the use of economic sanctions and the
aftereffects of the war in the Middle East. Duffey also evaluates the
use of military force to overcome the ethnic conflicts in Bosnia and
Somalia and recent successful resolutions.
