Japan’s Decision for War
Japan’s Objective: Preeminence in Asia
“Greater East Asia Co-Prosperity Sphere”
Shortage of oil was the key to Japan's Grand Strategy
Major consideration in preparing for war , yet
Key reason for going to war
Japan’s Decision for War
Japanese Strategy
• Neutralize US Pacific fleet and threats from the Philippines
• Establish defensive perimeter
• Use new resources to build capability to defend indefinitely
Felt US would be unwilling to pay cost of overcoming these defenses
Felt US would compromise, allow Japan the dominant position in Asia
Japan’s Decision for War
Calculated Risk or Risky Calculation?
Japanese Miscalculations
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
One man’s limited war may be another man’s total
war
Attack on Pearl Harbor
Breaks in our favor:
Two aircraft carriers at sea
Submarines, fuel stores not attacked
Repair facilities intact

WW II – Society At War: The Home Fronts
Lesson 17
WW II -- Combined Bombing Offensive
Total War
Total war: one in which the whole population
and all the resources of the combatants are
committed to complete victory
… and thus become legitimate military targets
… and rules of war are ignored.

Hugh Bicheno
Oxford Companion to Military History
Targeting Philosophy
U.S.:
Daylight, high-altitude precision bombing against specific
industrial targets
British:
Night area-bombing of cities
Together:
Combined Bomber Offensive
Strategic Bombing
Challenge
Selecting the most productive target sets
Initially
• U-boat facilities
After June 1943
• Fighter aircraft
• Ball bearings
• Petroleum
Prior to D-Day
• Transportation
Critique of Bombing Campaign
Established a “Second Front”
Precision bombing: results disappointing
Impact on morale: ultimately telling
• German experience different from British during Blitz
"Bombing appreciably affected the German will to resist. Its main
psychological effects were defeatism, fear, hopelessness, fatalism, and
apathy. It did little to stiffen resistance through the arousing of aggressive
emotions of hate and anger. War weariness, willingness to surrender, loss
of hope in German victory, distrust of leaders, feelings of disunity, and
demoralizing fear were all more common among bombed than among
unbombed people."
US Strategic Bombing Survey, European War
Critique of Bombing Campaign
Established a “Second Front”
Precision bombing: results disappointing
Impact on morale: ultimately telling
Impact on war production
• German production increased through mid-1944
• Late decision to mobilization
• Fighter production displaced bombers
• 85% of US bombs dropped after D-day
• Influenced final ground war after January 1945

Attacking Germany
The Plan
British Montgomery
US - Patton
Attacking Germany
The First Problem: Logistics
Only
Ports
September 1944
Logistics Challenges
Only operational ports: Cherbourg & Normandy beaches
Supply lines stretched over hundreds of miles
• Not enough trucks to fill pipeline and provide needed supplies
Units in combat required huge amounts of material
• One division in combat required 700-750 tons/day
• Average of 28 divisions north of the Seine after Paris liberated
Problem: How to deliver the goods with the trucks available?
Attacking Germany
Problem: Who gets the supplies?
British Montgomery
US - Patton
Operation Market-Garden
Combined (US-British) attempt to flank the Siegfried Line
• Operation Market: airborne assault to secure bridges
• Operation Garden: ground ops to relieve airborne within 4 days
Market-Garden
After Thoughts
Underlined the precarious nature of all airborne assaults
Major considerations:
Airlift available for initial insertion & resupply
Likelihood of timely relief by ground forces
Availability of fire support (organic or air)
Intelligence
WEATHER
Success = Good Planning & Luck!
