Roosevelt's case for preparation and sea power

Theodore Roosevelt's naval history sets out his case for preparedness and offensive sea power. He argues that an unprepared navy invites disaster and that a purely defensive posture cannot defeat a blockade. His comparison of British, French, and American performance gives professional training more weight than claims about national character. Modern warships were complicated systems whose officers and crews needed years of intelligent practice. Roosevelt carried this emphasis on a trained, usable fleet into his approach to American sea power.
