Students examine the circumstances that lead people to engage in or justify a war, the impact of war on ordinary people and military costs, and look at the issue of whether or not weapons of mass destruction should be allowed. Using the actual words of people with direct experience, expert views and statistics, useful graphs and eye-catching photographs, this volume brings this much-debated issue into a clearer perspective. Includes full-color photographs, time line, glossary, resources, and index. 46 pages.
