Carew examines the middle years of FDR’s presidency. Whereas other scholars have criticized FDR's leadership during these years, Carew considers these Roosevelt's most effective years because the president 'recalibrated the priorities of his administration' to meet challenges from abroad. The historiography of this period is more complex than Carew claims, but he presents a competent, textbook-style study of Roosevelt’s policies from 1938 to 1942, making references to FDR's naval expertise. FDR was determined to avoid Wilson’s mistakes, particularly the lack of preparedness that hampered the US war effort in 1917. Roosevelt worked in these middle years to convince the US public to aid those fighting the Axis and to mobilize the US economy to make the necessary supplies while increasing the strength of the US military. During this time, he also crafted a new US military and defense strategy, one designed to achieve total victory over the enemy. It is this strategy that Carew analyzes. After Pearl Harbor, FDR undertook to lead the allied coalition and ensure a postwar world based on US principles, a task Carew claims FDR completed with the 1943 Casablanca Conference. Carew's connections between the two wars will interest nonspecialists. Summing Up: Recommended. Lower- and upper-division undergraduates; general readers.
