On the Origins of War

A brilliant and vitally important history of why states go to war, by the acclaimed, award-winning author of The Peloponnesian War. 
War has been a fact of life for centuries.

Vivid, incisive, and accessible, Kagan''s powerful narrative warns against complacency and urgently reminds us of the importance of preparedness in times of peace.
