From Isolation to Leadership is an American history book that appeared in October, 1918, a few weeks before the signing of the Armistice, when the United States was at the high tide of its power and influence. In view of the subsequent course of events, some of my readers may question the propriety of the original title. In fact, one of my friends has suggested that a more appropriate title for the new edition would be "From Isolation to Leadership, and Back."
