THE Navy grows too introspective and so tends to forget that in war the military part of the national exertion is but a fraction of the whole. Did the Navy fully realize this fact, it would seriously ponder the question that at once arises: what steps have been taken to assure that the military part is properly coordinated with the other parts of the national exertion; or, to put it the other way, what steps have been taken to assure that the other parts of the national exertion are properly coordinated with the military effort? Cooperation is a fundamental principle of success. When we so carefully subject all naval plans to the searching test of this principle, how much more important it is to make sure that the whole national plan meets the principle. This paper is an attempt to inquire into the proper roles to be played by the statesman and the sea officer in the tragedy of war; an attempt to discover how each in playing his role may bring the drama to a successful conclusion.
