How can peace be realized in the modern world? And how can Japan ensure its own security? Despite the intense debates over Japan's security-related legislation, such vital issues as these have been ignored. To give proper consideration to these thorny questions, it is best to have both a knowledge of history indicating the circumstances in which wars occur and a real recognition of the security environment of the twenty-first century. This book explores hotly debated security-related matters from a standard viewpoint on international politics and diplomatic history. The author also outlines the form Japan's security should take and the path Japan should follow to make this a reality.--adapted from jacket.
