America’s Forgotten War

Origins: Civil War in China

Recall: During the age of imperialism, China was divided under “Spheres of Influence.”

Recall: Japan invaded China (Manchuria) during 1930s, WWII.

to building a strong country.– Two sides fought in a long Civil War!

• Outcome: Communists win in 1949!

also expanded into Korea.• Reaction: Most Koreans

became nationalistic.– Outcome: Plans for Korean

independence were never worked out before the fall of Japan.

• Temporary Solution?– Korea divided at 38th

advance past Korean border.– MacArthur does anyway.

• “Home By Christmas”

– China backs North Korea, pushes South Korean and US forces back to 38th parallel.

• Invade China?– MacArthur wants to back

the Chinese Nationalists Army (Taiwan) in an “invasion” of China.

• Truman opposes, fears widespread war in Asia.
