Japanese Expansion Japan was becoming overcrowded and lacked raw materials Solution: Build an empire 1931- Japan takes over Manchuria 1937 – Japan invades China The battle in China was costing $ and Japan needed resources so they set their sites on the rich Southeast Asian colonies

US Response to Expansion 1) After Japan invaded China in 1937, Roosevelt decided he had to speak out He urged the US to work with ‘Peace loving countries to quarantine aggressive nations and stop the spread of war’ 2) Sent aid to China to protect Guam and Philippines (US colonies) 3) 1941- cut off oil shipments to Japan

Inevitable War? US realized that cutting off oil supplies might lead to war Japan allied with Italy and Germany Upset over how the US was treating them Bitter about being ignored at the Treaty of Versailles Hideki Tojo (Japanese Prime Minister) very hostile toward US
