28 Japan’s Decision for War Japan’s Objective: Shortage of oil was the key to Japan's Grand Strategy Major consideration in preparing for war Key reason for going to war, yet “Greater East Asia Co-Prosperity Sphere” Preeminence in Asia

29 Japan’s Decision for War Japan saw a move to the south as its only option Realized this might force confrontation with US Would need to occupy, exploit Southeast Asia and East Indies By 1940, War in China had been dragging on for three years Growing size of Japanese military was draining scare resources Defeat at Khalkin Gol (1939) had discourage expansion into Siberia Planning for war with western powers began Summer 1940 Fall of Netherlands, France in May-June 1940 provided opportunity

30 Japan’s Decision for War Considered possibility of not going to war with US Initially believed: Finally convinced themselves US would go to war if they went south War in Europe favored Japan’s position Germany would never invade England US would not focus on Japan with European war in doubt, and

31 Japan’s Decision for War Japanese Strategy Neutralize US Pacific fleet and threats from the Philippines Felt US would be unwilling to pay cost of overcoming these defenses Felt US would compromise, allow Japan the dominant position in Asia Establish defensive perimeter Use new resources to build capability to defend indefinitely

32 Japan’s Decision for War Decision: Did not seek total defeat of US Had no intention of invading Planned to fight a war of limited objectives Having secured objectives, Japan would set up a defense in depth (Slide 4) Based on expectation that US would rather negotiate than fight Felt US would negotiate rather than fight a long, costly war Decisive preemptive attack on US Pacific fleet

33 Japan’s Decision for War Japanese Rationale Calculated Risk or Risky Calculation? Convinced by trade embargoes US was dedicated to thwarting Japan Felt Japan had no future without preeminence in Asia ( PM Tojo et al) Preeminence required going to war for resources Japan needed to go to war while it still had the power Believed defeat would be better than “humiliation and submission” (oil) Decision to go to war made July 2, 1941 by an Imperial Conference

34 Japan’s Decision for War Japanese Miscalculations Calculated Risk or Risky Calculation? One man’s limited war may be another man’s total war Did not anticipate US reaction to Pearl Harbor attack Assumed US would accept Japan’s limited war objectives Assumed they could keep the war limited
