Japan and Aggression
Japan continuing to acquire territories in the Pacific.
Indochina 1940Japan’s “offer” 1940America insults Japan: 1941
Why?
“Japan could not hope to win an all out war against America and Britain” Admiral Yamamoto (head of Japanese Military”
Deficits per Japanese estimates: Steel production capabilities: 20:1 Oil production capabilities: 100:1 Coal production: 20:1 Aircraft production (prewar) 5:1 Shipping: 3:1 Overall: 10:1
General Iwakuro
Did FDR know?
From Chief of Staff: George Marshall“the Oahu fortress complex (Pearl Harbor) is
the strongest in the world, a seaborne attack is out of the question”.
Part of the surprise was how outrageously ambitious the plan was.
Quick stats
First planes hit: 7:55 AMAll but 29 Japanese planes returned½ of America’s military fleet destroyed8 battleships destroyed3 cruisers2323 servicemen killed
Yet a total failure
Ships were quickly raised and repairedThe American carriers the key—were out oat
the time and remained safe.Submarine pens and oil storage tanks
unharmed“limited success was a woefully small military
return for the political risk of attacking the United States before a declaration of war” Paul Johnson.
The result?
America rallied and mobilized as quickly and as dominantly as any nation in human history.
Consider the numbers… Total growth:
By the end of the first year of the war…the US was now production as much as all the enemies and allies put together. By 1944 they had doubled their lead in that stat.
Tank growth: 1940: 24,000—1942: 58,000
Numbers
Soliders Enrolled:
11,260,000 troops 670,000 marines 4,200,000 sailors
An increase from an over at just over 2,000,000 in 1941!
Production US factories built by wars end
298,000 planes 102,000 tanks 88,000 ships
Growth at a miraculous pace
USS Yorktown 3 month job to repair, after Pearl Harbor—that was
moved up slightly…48 hours.Pentagon
7.5 year building plan—shaved to a yearShip building
1940 US building a ship in 196 days By 1942: 10.3 hours 52% of all ships produced in factories that were not
even there before Pearl Harbor!!!!
Japanese perspective…
Hirohito: “Why is it that it took the Americans only a few days to build a complete airbase and the Japanese more than 40 days?”
Admiral Nagano: “I am very sorry”
