Enlighten us... what 'brilliance' did FDR show during WWII as CIC?
He rebuilt American infrastructure during the great depression via the CCC and the WPA and other New Deal Programs. That played a critical role in support the war effort and it made rapid mobilzation to a war time economy possible.
He fought against the isolationist and the limitations of the Neutrality act and saw the critical and strategic importance of doing so.
He understood the serious threat that Nazi Germany represented to America far ahead of most of the nation. He prepared the nation and guided them towards a war time footing via his fireside chats, press conferences and with his unflinching leadership sold the American public that we should be the arsenal for democracy.
He implemented an arms embargo against the axis powers in 1936.
IN 1937 in anticipation of war he secretly began to build up the US Navy's submarine service to be able to quarentine enemy naval forces. A decision that had substantial consequences against Japan and their naval forces.
In 1939 he implemented the "Cash and Carry" program in which he was able to supply our allies, particularly the British, the arms they needed to stave off German invasion.
IN 1940 he established the nations first peace time draft.
He also signed the Destroyers for Bases act in which he publicly defied the neutrality act and provided Britain with 50 destroyers in return for US Rights to carribean naval bases.
In 1941 he spear headed the passage of the Lend Lease Act through congress and began sending massive aid to Great Britain, China and later the Soviets. Lend Lease played a critical role in staving off defeat for both Great Britain and the Soviets.
FDR's focus prior to the US involvement in WWII on preparedness and aid to our allies played a critical role in defeating the Axis powers.
He implemented the "Shoot on Site" policy towards any German Submarine that entered a US Naval zone.
He lead and concluded the Atlantic Charter in 1941.
He ordered the war department in 1941 to begin planning for total American war involvement under the "Victory Program" which provided his administration the data that was needed for total mobilization. A plan which included the mobilization, training and supplying of 10 million men in arms.
He requested congress to enact legislation that would dramaticlly tax corporate and individual war profiteering that provided an additional 10 billion annually to the war effort.
He declared war on Japan after the Pearl Harbor attacks and roused the nation with one of the all time great speeches "A date which will live in infamy" in US History.
and this is just the beginning. This doesn't even list his war planning and strategy and the vision he had to invest billions in spending programs like the Manhattan project and the B29 Bomber project which ushered the US into the atomic age. Should I continue?
