Conflict in the Pacific Flashcards
Economic Issues in the Pacific
- Japan wanted autarky to support expansion, population and modernisation
- Japan’s lack of raw materials meant they relied on imported materials (50% of iron core from Malaya, 90% of oil from US, 1/3 of cotton from India)
- European powers still suffered from post-war recession and Great Depression
- US was struggling against Depression but was global economic giant and had economic interests in Asia-Pacific
Political Issues in the Pacific
- Japan had unstable limited liberal democracy in 1920s but militant government took over in 1930s which directed itself towards Pacific
- Japan had fear of Seiryoku-tozen so ultranationalism and militarism were widespread
- Washington Conference restricted Japan but ships were more concentrated whilst US and Britain’s were dispersed
- Japan left League of Nations in 1933 after 1931 Manchuria Incident and abrogated Washington Conference
- Japan and Germany signed 1936 Anti-Comintern Pact
- Britain and France were still weak from WWI and interwar issues
- US had isolationist foreign policy
Japanese Foreign Policy from 1937-1941
- Motivated by economic needs, growing population and fervent nationalism
- Built on principles of kokutai, bushido and hakko ichiu
- Needed resources, ports in China and airfields in Pacific
- Expansion into China after 1937 Marco Polo Bridge Incident led to Rape of Nanking and Second Sino-Japanese War
- Japan signed 1936 Anti-Comintern Pact with Germany
- Germany and Soviets signed 1939 Molotov-Ribbentrop nonaggression pact so Japan felt threatened as Russia was more mechanised and could influence Asia (aided China and was victorious in conflict on Mongolian-Manchurian border)
- Signed 1940 Tripartite Pact with Germany and Italy
- Signed 1941 Neutrality Pact with Soviets
- Sought to take advantage of European preoccupation with war to seize colonies
- Needed Indochina for rubber/tin/oil/rice, airfields and strategic prevention of American supplies from reaching China
- Pressured Vichy France to allow Japan to occupy Tonkin (north Vietnam) in 1940, pressured to occupy Cochin-China (south Vietnam) in 1941 and took control
J.M. Roberts quote on Japanese Foreign Policy from 1937-1941
“The crux of the matter was Japan’s need for oil”
US Policies in the Pacific from 1937 – 1941
- 1935-39 Neutrality Acts prevented US involvement in wars
- Wanted to maintain Open Door Policy
- In 1941 after Indochina incident, US froze Japan’s assets, issued trade embargoes, reduced trade by 75%, stopped 90% oil exports and then eventually all oil
British Policies in the Pacific from 1937 – 1941
- Supported US economic policy towards Japan by imposing economic sanctions, stopping oil shipments and freeze assets after Indochina incident
- Pressured by Japan to close Burma Road that connected India to Chinese border so China unable to get supplies whilst fighting Japan
- Racist belief that Japanese were bad pilots due to myopia and inner ear defects
Course of the Bombing of Pearl Harbour
- 7 December 1941
- Attacked by 183 Japanese aircraft
- 8 battleships damaged/destroyed
- 11 warships damaged/sunk
- 50% of planes in Hawaii (over 300) destroyed or disabled
- Over 2000 US casualties
- US aircraft carrier fleet was avoided as it was not at Pearl Harbour
- Unable to destroy vast fuel supplies
Reasons for the Bombing of Pearl Harbour
- 1941 Hull Agreement was presented by US demanding removal of Japanese forces from Indochina and China, and pressuring Japan to leave Axis and sign non-aggression pacts with west
- Japan was encircled by ABCD (America, Britain, China, Dutch) and could not access resources in Pacific
- US had imposed trade sanctions on Japan
- Possibility of destroying US fleet was advantageous to Japan’s interests because it was the only threat to their expansionism (isolationalist policy, other countries involved in war) and the fleet would take 12 months to be replaced so US would be unable to help Allies and Japan could seize Western colonies
- Japan would have Pacific defensive perimeter by the time US fleet was replaced
- Japan would have raw materials from colonies to fight war against US
David Kennedy’s quote on the Bombing of Pearl Harbour
“masterful, though incomplete, tactical achievement”
US Response to the Bombing of Pearl Harbour
- US declared war on Japan on 8 December 1941
- America originally supported Allies in WWII indirectly through weapons/supplies but bombing changed made them directly involved in fighting
- 18 April 1942 Doolittle Raid after bombing and Philippines surrender boosted US morale and Japan became uneasy, felt undefended, questioned ‘victory disease’
- 120 000 Japanese-Americans incarcerated in internment camps for entire war
- Bombing utilised as propaganda tool for remainder of war through slogan “Remember Pearl Harbour”
