After World War I ended (November 1918), the number of strikes increased to record levels in 1919, with more than 3,600 separate strikes by a wide range of workers, e.g. steel workers, railroad shop workers, and the Boston police department. The press portrayed these worker strikes as "radical threats to American society" inspired by "left-wing, foreign ''agents provocateurs''". The IWW and those sympathetic to workers claimed that the press "misrepresented legitimate labor strikes" as "crimes against society", "conspiracies against the government", and "plots to establish communism". Opponents of labor viewed strikes as an extension of the radical, anarchist foundations of the IWW, which contends that all workers should be united as a

Historian Richard Powers distinguishes two main forms of anti-communism during the period,
liberal anti-communism and countersubversive anti-communism. The countersubversives, he argues, derived from a pre-WWII isolationist tradition on the right. Liberal anti-communists believed that political debate was enough to show Communists as disloyal and irrelevant, while countersubversive anticommunists believed that Communists had to be exposed and punished.
At times, countersubversive anticommunists accused liberals of being "equally destructive" as Communists due to an alleged lack of religious values or supposed "red web" infiltration into the

, creating the "
Federal Employees Loyalty Program" establishing political-loyalty review boards who determined the "Americanism" of Federal Government employees, and requiring that all federal employees to take an oath of loyalty to the United States government. It then recommended termination of those who had confessed to spying for the Soviet Union, as well as some suspected of being "Un-American". This led to more than 2,700 dismissals and 12,000 resignations from the years 1947 to 1956.
It also was the template for several state legislatures' loyalty acts, such as California's
Levering Act. The House Committee on Un-American Activities was created during the Truman administration as a response to allegations by Republicans of disloyalty in Truman's administration.

ed. Critics of the HUAC claim their tactics were an abuse of government power and resulted in a witch hunt that disregarded citizens’ rights and ruined their careers and reputations. Critics claim the internal witch hunt was a use for personal gain to spread influence for government officials by intensifying the fear of Communists infiltrating the country. Supporters, however, believe the actions of the HUAC were justified given the level of threat Communism posed to democracy in the United States.
Senator McCarthy stirred up further fear in the United States of communists infiltrating the country by saying that communist spies were omnipresent, and he was America's only salvation, using this fear to increase his own influence. In 1950 Joseph McCarthy addressed the senate, citing 81 separate cases, and made accusations against suspected communists. Although he provided little or no evidence, this prompted the Senate to call for a full investigation.
Senator
Pat McCarran (
D.,
Nev.) introduced the
McCarran Internal Security Act
The Internal Security Act of 1950, (Public Law 81-831), also known as the Subversive Activities Control Act of 1950, the McCarran Act after its principal sponsor Sen. Pat McCarran (D-Nevada), or the Concentration Camp Law, is a United States f ...
of 1950 that was passed by the U.S. Congress and which modified a great deal of law to restrict civil liberties in the name of security. President Truman declared the act a "mockery of the Bill of Rights" and a "long step toward totalitarianism" because it represented a government restriction on the freedom of opinion. He vetoed the act but his veto was overridden by Congress. Much of the bill eventually was repealed.

, especially those of
Chinese or
Korean descent, came under increasing suspicion by both American civilians and government officials of being Communist sympathizers. Simultaneously, some American politicians saw the prospect of American-educated Chinese students bringing their knowledge back to "Red China" as an unacceptable threat to American national security, and laws such as the China Aid Act of 1950 and the
Refugee Relief Act of 1953 gave significant assistance to Chinese students who wished to settle in the United States. Despite being naturalized, however, Chinese immigrants continued to face suspicion of their allegiance. The general effect, according to

scholar Qing Liu, was to simultaneously demand that Chinese (and other Asian) students politically support the American government yet avoid engaging directly in politics.
The Second Red Scare profoundly altered the temper of American society. Its later characterizations may be seen as contributory to works of feared communist espionage, such as the film ''
My Son John'' (1952), about parents' suspicions their son is a spy. Abundant accounts in narrative forms contained themes of the infiltration, subversion, invasion, and destruction of American society by un–American ''thought''. Even a baseball team, the

, temporarily renamed themselves the "Cincinnati Redlegs" to avoid the money-losing and career-ruining connotations inherent in being ball-playing "Reds" (communists). In 1954, Congress passed the
Communist Control Act of 1954, which prevented members of the communist party in America from holding office in labor unions and other labor organizations.
Wind down
Examining the political controversies of the 1940s and 1950s, historian
John Earl Haynes, who studied the
Venona decryptions extensively, argued that Joseph McCarthy's attempts to "make anti-communism a partisan weapon" actually "threatened
he post-Waranti-Communist consensus", thereby ultimately harming anti-communist efforts more than helping them.
Meanwhile, the "shockingly high level" of infiltration by Soviet agents during WWII had largely dissipated by 1950.

has."

In 1954, after accusing the army, including war heroes, Senator Joseph McCarthy lost credibility in the eyes of the American public and the
Army-McCarthy Hearings were held in the summer of 1954. He was formally censured by his colleagues in Congress and the hearings led by McCarthy came to a close.
After the Senate formally censured McCarthy, his political standing and power were significantly diminished, and much of the tension surrounding the idea of a possible communist takeover died down.
From 1955 through 1959, the Supreme Court made several decisions which restricted the ways in which the government could enforce its anti-communist policies, some of which included limiting the federal loyalty program to only those who had access to sensitive information, allowing defendants to face their accusers, reducing the strength of congressional investigation committees, and weakening the Smith Act.
In the 1957 case ''
Yates v. United States'' and the 1961 case ''
Scales v. United States'', the Supreme Court limited Congress's ability to circumvent the First Amendment, and in 1967 during the Supreme Court case ''
United States v. Robel'', the Supreme Court ruled that a ban on communists in the defense industry was unconstitutional.
