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
In 1924,

Foreign Policy: Economic Policy
■But the Great Depression made
post-war recovery in Europe
difficult in the 1930s:
–The Hawley-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

of Nations, but did play a role in
attempts to avoid future wars:
–At the Washington Disarmament
Conference in 1921, world
leaders agreed to disarmament,
free trade, & collective security
–In 1928, almost every nation,
including the USA, signed the
Kellogg-Briand Pact, renouncing
war as a tool of foreign policy
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
Totalitarian Regimes:
Hideki Tojo & Emperor Hirohito
In 1937,Japan
Japanese
pilots bombed
the USS Panay,
Invades
Manchuria
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
Totalitarian Regimes: Benito Mussolini
Totalitarian Regimes: Hitler
The Munich Pact
“Peace in our time”
Rome-Berlin-Tokyo Axis
Foreign Policy: International Peace
■In the 1930s, FDR & Congress
were too preoccupied with the
Great Depression to adequately
plan for new world conflicts

desire to avoid involvement in
another world war

Americans wanted to avoid
another “meaningless war”
