American Isolationism & Foreign Policy
in the 1920s & 1930s

Foreign Policy in the 1920s & 1930s■After WWI, the U.S. assumed a selective isolationist foreign policy
–Americans wanted to maintain the economic boom of the 1920s & were desperate for an answer to the depression in the 1930s
–But, the U.S. did play an active role in attempts at international disarmament & economic stability

Foreign Policy: Economic Policy■In the 1920s, the most divisive
international issue was war debts:–European nations owed the U.S.
$10 billion; Attempts to reclaim these debts led to anti-American sentiment in Europe
–When Germany could not repay $33 billion in reparations, the U.S. negotiated the Dawes Plan
The U.S. Foreign Debt Commission canceled a large portion of these debts, but insisted that some of the money be repaid
In 1924, Hoover negotiated a reduction in German debt, an extended time period to
repay debts, & U.S. loans to help Germany make payments to France & England
The Dawes Plan helped stabilize the German economy, allowed Germany to repay the
Allies, and helped France & England repay their debts to the United States

Foreign Policy: Economic Policy■But the Great Depression made
post-war recovery in Europe difficult in the 1930s:–The Hawley-Smoot TariffHawley-Smoot Tariff in
1930 limited European attempts to sell their goods in the U.S.
–The U.S. was unable to provide loans, leaving Germany unable to repay reparations & Europe unable to repay its war debts
![Page 7: ■Essential Question ■Essential Question: –What factors led the United States to shift from isolation in the 1920s & 1930s to an active war participant](https://reader034.vdocument.in/reader034/viewer/2022051214/56649e3f5503460f94b303d9/html5/thumbnails/7.jpg)
Foreign Policy: International Peace■The USA never joined the League
of Nations, but did play a role in attempts to avoid future wars:–At the Washington Disarmament Washington Disarmament
ConferenceConference in 1921, world leaders agreed to disarmament, free trade, & collective security
–In 1928, almost every nation, including the USA, signed the Kellogg-Briand PactKellogg-Briand Pact, renouncing war as a tool of foreign policy
The USA, England, Japan, Italy, & France signed the Five-Power Treaty & agreed to limit
construction of battleships & aircraft carriers
The Nine-Power Treaty reaffirmed the Chinese Open-Door Policy
England, USA, Japan, France signed the Four-Power Treaty agreeing to collective security
But, neither the Nine- or Four-Power Acts had provisions to enforce these agreements

Foreign Policy: International Peace■These agreements did not last:
–Japan needed raw materials to continue its industrial expansion
–Japan began to create an Asian empire by attacking Manchuria in 1931 & China in 1937
–In both occasions, the League of Nations reprimanded Japan but chose no punitive measures

Japan Invades ManchuriaIn 1937, Japanese pilots bombed the USS Panay, a U.S. gunboat stationed in China, killing 3
Americans. The U.S. accepted Japan's apology & promise against future attacks
Unlike the USS Maine or Lusitania, few Americans called for war against Japan

Foreign Policy: International Peace
■In the 1930s, FDR & Congress were too preoccupied with the Great Depression to adequately plan for new world conflicts involving totalitarian dictators
■The rising threat of war in Europe & Asia strengthened Americans’ desire to avoid involvement in another world war
![Page 17: ■Essential Question ■Essential Question: –What factors led the United States to shift from isolation in the 1920s & 1930s to an active war participant](https://reader034.vdocument.in/reader034/viewer/2022051214/56649e3f5503460f94b303d9/html5/thumbnails/17.jpg)
Foreign Policy: Citizen Attitudes■In the 1920s & 1930s, most
Americans wanted to avoid another “meaningless war”–Munitions makers & bankers
were labeled “merchants of death” & were blamed for American involvement in WWI
–Passivism swept across college campuses; Students staged “walk-outs” & anti-war rallies
Historian Walter Millis’ America’s Road to War blamed Wilson & British propaganda
for “duping” the U.S. into WWI

The Neutrality Acts■The “merchants of death” charges
were led by North Dakota Senator Gerald Nye from 1934 to 1936:
–Reaction to the Nye CommitteeNye Committee report led to popular support to avoid making the same mistakes that led America to enter WW1
–Congress passed 3 neutrality acts to avoid future wars
The Neutrality Act of 1935 banned arms sales to nations at war & warned citizens not to sail on belligerent ships
The Neutrality Act of 1936 banned loans to any warring nation
The Neutrality Act of 1937 made the 1935 & 1936 acts permanent

From Neutrality to Undeclared War■As Europe headed toward war,
FDR openly expressed his favor for intervention & took steps to ready the U.S. for war–In 1937, FDR unsuccessfully
tried to convince world leaders to “quarantine the aggressors”
–Everything changed in 1939 with the Nazi-Soviet Pact & the German invasion of Poland
But…FDR was able to get $1 billion from Congress to expand the U.S. navy

From Neutrality to Undeclared War■When WW2 began in 1939,
Congress imposed a cash & carry cash & carry policypolicy to aid the Allies:–The U.S. would trade with the
Allies but would not offer loans –The U.S. would not deliver
American products to Europe■In addition, FDR traded 50 old
destroyers with England for 8 naval bases in Western Europe
“The destroyer-for-bases deal is the most important action in the reinforcement of our national defense that has been taken
since the Louisiana Purchase” —FDR
FDR responded with all-out aid to the Allies but did not call for war
Still attempting to avoid more “merchants of death” in the banking industry
Still attempting to avoid losing American lives at sea by German submarines
Which eased the rigid restrictions of the Neutrality Acts of 1935-1937 to
allow the US to aid England & France

From Neutrality to Undeclared WarIsolationists
■ Were appalled by this departure from neutrality & FDR’s involvement of the U.S. in foreign war
■ Their “fortress of America” idea argued that Germany was not a threat to the U.S.
Interventionists■ Groups like the
Committee to Committee to Defend America by Defend America by Aiding the AlliesAiding the Allies called for unlimited aid to England
■ They argued that the events in Europe did impact the security of U.S.

From Neutrality to Undeclared War■By 1940, “interventionists” had
the majority of American public sentiment on their side:–in 1940, Congress appropriated
$10 billion for preparedness–FDR called for America’s first
ever peacetime draft–In the election of 1940, FDR
was overwhelmingly elected for an unprecedented 3rd term

From Neutrality to Undeclared War
■By 1940, England remained the only active opposition to Hitler but was running out of money
■FDR called for a Lend-Lease ActLend-Lease Act:–U.S. can sell or lend war
supplies to Allied nations–Congress put $7 billion to allow
England full access to U.S. arms

From Neutrality to Undeclared War■England desperately needed help
escorting U.S.-made supplies through the u-boat infested Atlantic–FDR allowed for U.S. patrols in
the western half of the Atlantic–German attacks on U.S. ships in
1941 led to an undeclared naval war between USA & Germany

From Neutrality to Undeclared War■In 1941, FDR & Churchill met to
secretly draft the Atlantic CharterAtlantic Charter:
–The U.S. & Britain discussed a military strategy if the USA were to enter the war
–They discussed post-war goals of free trade & disarmament

From Neutrality to Undeclared War■FDR brought U.S. to the brink of
war & opened himself to criticism:
–In Sept 1941, polls showed 80% of Americans supported remaining neutral in WW2
–FDR had to wait for the Axis to make a decisive move…which Japan delivered on Dec 7, 1941

with fuel, iron, & oil sanctions

Showdown in the Pacific■In 1941, the U.S. & Japan were
unable to diplomatically resolve their differences, so the USA:
–Froze all Japanese assets in USA
–Banned all oil sales to Japan
■Hideki Tojo sent an envoy to negotiate for a resolution…but secretly ordered an attack on the U.S. naval base at Pearl Harbor
U.S. wanted the Japanese removed
from China
Japan wanted an end to sanctions & a free
hand to China
This was really a stall tactic intended to hide Japanese military preparations
for an attack on Pearl Harbor

Showdown in the Pacific■After Pearl Harbor:
–Congress declared war against Japan on Dec 8, 1941
–Italy & Germany declared war on the U.S. on Dec 11, 1941
■American public opinion was now fully behind the war effort to defeat the fascist threat in Europe & to seek revenge against Japan
…but Germany was still seen as the primary danger
The U.S. now faced a possible 2-ocean war…
