Second, the just war theory offers a common moral framework and language with which to discuss issues of war in the public arena. As Christians and as citizens it gives us a starting point for discussion and cultural engagement. Third, just war theory gives moral guidance to individuals in developing their conscience, responsibilities, and response. When the war drums sound, they are often loud and there is frequently confusion, competition, and chaos rather than clear thinking about the moral and biblical consequences of what is occurring. Just war theory is a tool for responsible Christian living and citizenship.
War is a multi-faceted event with multiple causes.
Often what keeps a war going is different from what started it. Once wars begin, they follow a unique course all their own. Yet, the definition and the experience of war are two vastly different things. In World War II more than half of all war deaths were noncombatants. Today, at the end of the twentieth century, more than three-fourths of all war deaths are civilians.
