Here is an original and up-to-date account of a key period of military history, one that not only links the two World Wars but also anticipates the more complex nature of conflict following the Cold War. Black links the two World Wars, between the overcoming of trench warfare in the campaigns of 1918 and the fall of France in 1940. This was a period when militaries, governments and publics digested the lessons of the Great War and prepared for another major struggle. Black also locates the period in terms of long-term questions in military history, including the relationship between symmetrical and asymmetrical warfare, the tensions surrounding innovation, the pressures and possibilities created by technological change and the impact of ideology on the causes and conduct of war. Black's book devotes particular attention to the Far East as part of his worldwide coverage. He also assesses the role of the military in internal politics and establishes the importance of civil wars.
