A comprehensive account of Israel's doctrine of national security, this study examines to what degree security theories have proven valid and suggests an updated security doctrine for the next century. Beginning with the establishment of the state of Israel in 1948, Israeli defense planners have faced a daunting task. General Tal describes the history of the Israel-Arab wars from the War of Independence onward and presents a security theory specific to Israel from which the fighting doctrines of the Israeli military derive. He also to categorizes the levels of security various nations enjoy as a result of their differing geo-political situations, their power, and the conflicts of interests that they face with their neighbors.

This volume clarifies topics in the area of national security, the art of war, principles of war, and lessons learned from past conflicts. Tal concludes that previous security theory proved valid because it was based upon a decision to allocate the great portion of available resources, both intellectual and material, to secure national defense. However, this theory is no longer valid due to political changes in the Middle East and the development of modern military technologies. He asserts a new approach that rests upon mutual strategic deterrence throughout the region.
