The author, President of Brown University, has written this thought-provoking book on the theory that in time of war prepare for peace. Drawing on his wide range of historical knowledge, he shows how easy it is for victors in war to lose the ensuing peace through their failure to organize it on a sane and durable basis. He therefore urges that these lessons of the past be taken to heart by the men who will be responsible for making and keeping the new peace, however and whenever it comes.
