From the day of McKinley's death by an assassin's bullet, into the present, here is a work which shows the United States moving steadily if reluctantly into its position in the center of world leadership. Throughout hundreds and hundreds of pages every major political figure, every important international act or decision, move the country toward its present position. Long chapters are devoted to the real milestones of our international history---to the Great White Fleet, to Wilson and the Great War, to the causes of the Pearl Harbor tragedy, to Yalta. There is little editorial comment, little of style to distinguish the exciting from the prosaic. The acts speak for themselves. The result however is an overall text-bookish effect which does tend to tire. But even as a kind of textbook, it achieves a great deal. For scholar and lay reader alike, an excellent source of compressed information now waits their attention.
