This volume tells a very important part of the story of the Japanese Army and its part in dragging the nation into a catastrophic war. It is well and clearly written and generally quite strong in its sources. It is not the first book one should read about interwar Japan and its march to war, since it really does not present a rounded view of Japanese politics and the army as an institution. But for someone who understands the general background, it is fascinating and useful.
One caution: in common with many books written by specialists in Japanese history, it presents a very distorted picture of the mindset and actions of the Roosevelt administration. The central problem is an implicit assumption that Japan was the central concern when in fact its importance to FDR and his lieutenants lay in its relationship to the problem of Hitler. Deprived of this context, the actions of the administration are truly inexplicable.
