The Influence of McCarthyism (AQA A-Level History): Revision Notes
The Influence of McCarthyism
Context: Anti-communist fears in post-war America
By 1950, the USA faced mounting anxiety over the perceived communist threat. Two developments intensified this fear: the USSR's successful test of atomic weaponry in 1949 and China's transformation into a communist state that same year. In 1950, China allied with the USSR, creating the spectre of a unified communist bloc that appeared to threaten American security.
NSC-68 was a National Security Council document that characterised the Cold War as 'a real war in which the survival of the free world [was] at stake', demanding that Americans demonstrate 'ingenuity, sacrifice and unity'. This rhetoric reflected and amplified the growing paranoia within US society.
NSC-68 represented a pivotal moment in Cold War policy, transforming American foreign policy from containment to a more aggressive stance. The document's apocalyptic language helped create the climate of fear that McCarthyism would exploit.
The Rosenberg case
Julius and Ethel Rosenberg were convicted in March 1951 of passing American nuclear secrets to the USSR. Both received death sentences and were executed. During their appeal, their lawyer Arthur King observed that Judge Jerome Frank, described as a leading liberal judge, had become 'terrorised' by the prevailing climate of fear. King commented that Frank feared that showing leniency towards the Rosenbergs would result in accusations of communist sympathy, leading to his own prosecution.
Case Study: The Rosenberg Trial and Judicial Independence
The Rosenberg case demonstrates how McCarthyism compromised the independence of the judiciary:
The Situation: Julius and Ethel Rosenberg faced trial for espionage in 1951
The Evidence: Judge Jerome Frank, known as a leading liberal judge, faced immense pressure
The Outcome: Frank became 'terrorised' by fear of being labelled a communist sympathiser
The Impact: Even liberal judges felt compelled to impose harsh sentences to avoid accusations of disloyalty
This case illustrated how deeply anti-communist paranoia had penetrated American institutions, compromising even the independence of the judiciary.
McCarthyism in the USA
Anti-communist sentiment had existed among the American public throughout the post-war period, but intensified dramatically by 1950. The House of Un-American Activities Committee (HUAC) had already conducted extensive investigations into the political loyalties of Hollywood filmmakers and other high-profile figures. Founded in 1938 and made permanent from 1945, HUAC's stated purpose was to investigate communist infiltration. The committee operated on the assumption that communism represented an inherent threat to American society.
The Dark Side of HUAC's Operations
Those summoned before HUAC were often entirely innocent but became sacrificial victims who fed popular paranoia. The film industry became a particular target for investigation. Careers were destroyed based on allegations alone, without requiring substantial evidence of actual communist activity or espionage.
The Alger Hiss affair
Alger Hiss had served as a prominent member of Franklin D. Roosevelt's pre-war and wartime governments. In 1948, journalist Whittaker Chambers accused Hiss of being a communist and a member of the Communist Party. When Hiss was finally convicted of perjury in January 1950, his friend Dean G. Acheson publicly offered him support. This act intensified the belief among some Americans that the nation's leaders were somehow compromised by communist sympathies.
The Hiss case became a defining moment in Cold War America. His conviction seemed to validate fears of communist infiltration at the highest levels of government, providing McCarthy with ammunition for his later campaigns. The case demonstrated how a single high-profile conviction could amplify public paranoia and lend credibility to broader accusations.
Key figure: Joseph McCarthy
Joseph McCarthy (1909–57) was a Republican senator for Wisconsin. He ruthlessly exploited and intensified the anti-communist anxieties of the time. In 1954, having accused the US Army itself of being soft on communism, he was discredited.
McCarthy's Legacy: Destruction Without Evidence
McCarthy's 'reign of terror' ultimately failed to uncover even one government worker as an actual communist. Despite investigating thousands and destroying numerous careers, his entire campaign was built on unsubstantiated accusations rather than facts. This represents one of the darkest periods in American democratic history.
McCarthy's campaign and methods
McCarthy orchestrated sustained pressure on Truman's administration, designed to strengthen the government's stance towards what he portrayed as a communist global conspiracy threatening the USA. Drawing on the Alger Hiss affair, McCarthy promoted the notion that an army of communist conspirators was operating within the US government, influencing its policies.
In a speech delivered at Wheeling, West Virginia in February 1950 (later presented in modified form to the US Senate on 20 February 1950), McCarthy claimed:
"At the war's end we were physically the strongest nation on earth... Unfortunately we have failed miserably to rise to the opportunity. We find ourselves in a position of impotency, not because our only potential enemy has sent men to invade our shores, but because of the traitorous actions of those who have been treated so well by this nation... In my opinion the State Department, which is one of the most important government departments, is thoroughly infested with communists. We are dealing with a far more sinister type of activity because it permits the enemy to guide and shape our policy."
McCarthy's Rhetorical Strategy
This speech exemplified McCarthy's approach: presenting unsubstantiated claims as established facts whilst exploiting genuine American anxieties about national security. He never provided concrete evidence for his accusations, yet his inflammatory language resonated with a public already fearful of communist expansion.
McCarthy's targets
McCarthy pursued multiple targets during his anti-communist campaigns. Beyond the State Department, he attacked the film industry, the Democratic Party and universities. J. Edgar Hoover, head of the FBI during the McCarthy years, proved a notable figure. Hoover frequently referred to teachers as 'Reducators', referencing the nickname 'Reds' commonly used to describe communists. Hoover employed inflammatory rhetoric claiming that such individuals were undermining America's traditions and customs, and questioning the correctness of the American way of life. McCarthy also attacked the United Nations, accusing it of favouring left-wing and liberal causes. The Norwegian Secretary-General, Trygve Lie, did little to challenge these accusations.
McCarthy's downfall
In 1954, McCarthy made an overreach by claiming that 'Reds' had infiltrated the US Army. A skilful legal defence by army counsel Joseph N. Welch destroyed McCarthy. In a televised confrontation, Welch asked:
"Senator... you have done enough. Have you no sense of decency, sir? At long last have you left no sense of decency?"
The Army-McCarthy Hearings: A Turning Point
The Context: McCarthy accused the US Army of harbouring communists in 1954
The Televised Confrontation: Army counsel Joseph N. Welch confronted McCarthy during nationally televised hearings
The Famous Question: "Have you no sense of decency, sir?" - This moment exposed McCarthy's tactics to millions of Americans
The Outcome: In December 1954, the US Senate voted to censure McCarthy for bringing that body into disrepute
The Result: This action effectively ended McCarthy and the influence of those who had joined his anti-communist movement
The televised nature of these hearings proved crucial - Americans could see McCarthy's bullying tactics firsthand, turning public opinion against him.
The influence of McCarthyism on Britain and Europe
Despite the primarily domestic focus of McCarthyism, the phenomenon exercised notable influence on foreign relations. Historian Crockatt argues that 'the significance of McCarthy's career lies in the coincidence of his brief period of notoriety with the shift of attention from Europe to the Far East, a shift which he helped to promote'. McCarthyism emphasised the necessity of moving US policy away from a Eurocentric focus towards policies with a more determined 'Asia first' viewpoint.
The 'Asia first' policy shift
This reorientation proved particularly urgent following the creation of communist China in 1949 and the alliance of mutual cooperation formed between China and the USSR. McCarthy expressed concern that Truman's apparent indifference to communism's spread in Asia might become an element of the USA's Asia policy. McCarthy's anti-communist rhetoric coincided with Truman's reluctance to support Jiang Jieshi during the Chinese Civil War in the face of growing communist power. McCarthy promoted the view that the Korean War would not have occurred had Truman adequately supported the Chinese nationalists against Mao Zedong and recognised the ongoing threat of communist expansion in Asia.
Truman had attempted to resolve the Chinese Civil War by bringing communists and nationalists together rather than aiding the nationalists against the communists. This approach was rejected by those in America who already favoured the Eurocentric focus, and the McCarthy factor strengthened the shift towards a more clearly defined 'Asia first' policy.
British concerns about US policy
In terms of foreign relations, Britain could no longer maintain its early pre-war role as the USA's main partner in Europe. By the 1950s, Britain was becoming increasingly concerned about what it perceived as the USA's more aggressive Cold War thinking. Britain worried, for example, that the USA's aggressive stance over Korea might destabilise Europe whilst the international community focused on Asia. The USA's growing 'Asia first' thinking appeared dangerous from Britain's perspective. It also necessitated increased defence spending by Britain during a time of continuing austerity.
Britain's Dilemma
The conflict in Korea appeared, in the eyes of the British, to place in jeopardy the stability and territorial status quo that the creation of NATO had established. The globalisation of the USA's role did not align with what Britain saw as being in its interests. However, Britain's primary concern was to remain a close ally of the USA, and this assumed an overriding priority. Britain therefore made a notable military contribution to the allied war effort in Korea.
US dominance in the United Nations
The headquarters of the United Nations (UN) has always been in New York. Its location carried importance in terms of US dominance when the organisation was established.
The United Nations Charter was agreed in June 1945 and the organisation formally came into being in October 1945. The membership established in 1945 remained unchanged until 1955. The composition of the membership did not reflect the emergence of two ideologically divided strategic power blocs in international relations.
The Western Advantage in UN Membership
Of the 50 original members, 20 were drawn from capitalist Central and South American states. The members from the Middle East were also pro-Western. These included Iran, Iraq and Egypt. The pro-Western membership, and therefore the USA's natural ally, was further reinforced through the presence of Greece (a state that had triggered the introduction of the Truman Doctrine) and the majority of the USA's Western European allies along with India, Canada, Australia and New Zealand.
This composition gave the United States a significant advantage in UN voting during the early Cold War period, reflecting American influence in international institutions.
Key Points to Remember:
-
McCarthyism emerged from genuine fears - The USSR's atomic bomb (1949) and China's communist revolution (1949) created real anxiety in America, which McCarthy exploited through unsubstantiated accusations of widespread communist infiltration.
-
McCarthy's tactics destroyed lives without evidence - Despite investigating thousands and destroying numerous careers, McCarthy's 'reign of terror' never uncovered a single proven communist government worker, demonstrating the campaign was driven by paranoia rather than facts.
-
The 1954 Army-McCarthy hearings ended his influence - Army counsel Joseph N. Welch's famous question "Have you no sense of decency, sir?" exposed McCarthy's tactics on television, leading to Senate censure in December 1954.
-
McCarthyism shifted US foreign policy focus from Europe to Asia - The movement strengthened the 'Asia first' policy, emphasising threats in Asia (particularly China and Korea) over the previously dominant Eurocentric approach, creating tensions with Britain.
-
US dominance in the UN reflected Western Cold War advantage - Of 50 original UN members, the majority were pro-Western (including 20 Central and South American states), with headquarters in New York, reinforcing American influence in international institutions.
