International Security and War. Politics and Grand Strategy in the 21st Century [PDF ebook] 

This book studies both theoretical aspects of strategy and contemporary challenges to strategic thought. This is not only due to the enduring relevance of war in its various forms as a phenomenon in international relations, but can be attributed as well to the continuing relevance of competitive power politics on the world stage. Yet, it is far from certain that the currently renewed interest in strategy and strategic studies will persist in the years to come. This new book reviews research that focuses on the ability of strategic errors and false policy to reinforce the need for strategic expertise rather than serve as proof of the concept of strategy and the respective discipline.
