Why the U.S. Restricted Trade with Japan Before WWII
Pre-WWII U.S. trade restrictions on Japan stemmed from escalating geopolitical and economic tensions:
- Economic Competition: Japan's low-cost textiles, steel, and autos threatened U.S. industries.
- Protectionism: Smoot-Hawley Tariff (1930) raised barriers globally; Japan retaliated.
- Japanese Militarism: Invasion of Manchuria (1931), China (1937) alarmed Washington.
- Treaty Violations: Japan abrogated Nine-Power Treaty (1922) and Kellogg-Briand Pact (1928).
- Resource Race: Japan sought Dutch East Indies oil/rubber; U.S. backed Dutch control.
- Pacific Power Balance: U.S. aimed to check Japanese hegemony threatening its interests.
Escalating sanctions (oil embargo, asset freeze, 1941) cornered Japan, precipitating Pearl Harbor.
