The Iron
Iron Curtain:

spread further into Asia,
Africa and all of Europe
(Domino Theory).
■The Truman Doctrine offered
U.S. assistance to any nation

Marshall Plan
■European nations had

■The Marshall Plan offered
aid to help Europe recover
– Industry revived &
Western Europe became a

Truman and Korea
■In 1950, the government creates NSC-68:
– Pledged the U.S. not only to contain communism but to
liberate communist countries
– Recommended the expansion of U.S. military, stockpiling
nuclear weapons, & covert operations
• After WW2, Korea was divided along the 38 Parallel with
USSR in the North & the USA in the South
• Soviet-trained North Korea attacked across the 38° in 1950
and invades South Korea
• The U.S. sends troops to defend South Korea
• 1953 – Under President Eisenhower an armistice is signed
to end the Korean War
In the 1950s, President Eisenhower escalated the
Cold War by using brinkmanship: threatening to use
nuclear weapons & willingness to go to the brink of war
If the USSR
attacked a
NATO member,
the U.S. would
use massive
attack every
major Soviet city
& military target
As a result,
the USA & USSR
began stockpiling
nuclear weapons
& building up
their militaries
With the USA & USSR in possession of large nuclear
stockpiles, each side could destroy each other:
this was known as Mutually Assured Destruction (MAD)
Throughout the
Cold War, the
looked for ways
to gain first
strike capability
(Arms Race)
U.S.-Soviet relations changed in 1953 when Stalin died
after 30 years of absolute rule over the Soviet Union
In 1955, Khrushchev
Nikita Khrushchev
formed a communist
took over and began to
alliance to rival NATO,
aggressively challenge
called the Warsaw Pact
U.S. influence in the world
In 1956, the Soviet Union
threatened expansion
into the Middle East
President Eisenhower
responded with the
Eisenhower Doctrine,
pledging the USA to
protect the Middle East
from Communism
Fears of a nuclear attack and spread of communism
led to a Red Scare in the late 1940s & 1950s
Americans grew worried
about Communists
& Soviet spies living in
The Loyalty Review Board
was created to investigate
& dismiss “disloyal”
government employees
The House Un-American
Activities Committee
(HUAC) investigated
suspected communists
in the entertainment &
other industries
From 1947-1951, 3.2 million gov’t employees were
investigated & 212 were dismissed as security risks
(2,900 resigned rather than face investigation)
In 1947, numerous Hollywood writers & executives
were investigated by HUAC; 500 were blacklisted
from the film industry & some were sent to prison
for refusing to testify (the “Hollywood Ten”)
Red Scare fears in America were heightened by
the discovery of spies working for the USSR:
State Department
employee Alger Hiss
was convicted of
spying for the USSR
Julius & Ethel Rosenberg
were executed for passing
atomic bomb secrets to
the USSR
In 1950, Wisconsin Senator Joseph McCarthy emerged
as the leader of the anti-communist Red Scare
He attacked Truman for
allowing communists to
infiltrate the government
He used public trials
to make unsupported
accusations against
suspected communists in
the State Department &
the U.S. military
“McCarthyism” did not
result in a single
confirmed communist or
spy in the U.S. gov’t
To combat American fears of a nuclear attack, the
U.S. government responded in a number of ways
National and local
prepared citizens
for a Soviet nuclear
attack on the
United States
Citizens built fallout
shelters in their
Cities and schools
practiced building
evacuations and
“duck & cover” drills
In 1957, the USSR used Sputnik shocked Americans
its first ICBM to launch
who feared the U.S. had
Sputnik, the first
fallen behind the USSR in
satellite into space
science & technology
As a result of Sputnik, the Cold War escalated into a
space race to show American & Soviet dominance
