With the costs of war dominating our economic news and discussions, Paul Poast's new text is a needed, relevant and thought-provoking new offering. Written in an extremely accessible manner, the book is an interesting addition to a course at any level. The book's low price makes it a perfect complement to a Principles text, a Social Issues book, or any upper-level course on war or international security into which an instructor would like to add some economic data or theory.
