1.Shortly after WWII a phenomenon known as McCarthyism began to emerge in American politics.  McCarthyism was the practice of investigating and accusing persons in positions of power or influence of disloyalty, subversion (working secretly to undermine or overthrow the government), or treason. Reckless accusations that the government was full of communists were pursued by Republican-led committees with subpoena power and without proper regard for evidence. The two Republicans most closely associated with McCarthyism were the phenomenon's namesake, Senator Joseph McCarthy, and Senator Richard Nixon, who served as Vice President from 1953-1961,and then President from 1969-1974.  Both men were driven by personal insecurities as much as by political gain.  Government employees, the entertainment industry, educators, and union activists were the primary targets of McCarthyism.  Their communist (or leftist) associations were often greatly exaggerated, and they were often dismissed from government jobs or imprisoned with inconclusive, questionable, and sometimes outright fabricated evidence.  Most verdicts were later overturned, most dismissals later declared illegal, and some laws used to convict later declared unconstitutional.  The most famous examples of McCarthyismare the investigation into the leftist influence of the motion picture industry by the House Un-American Activities Committee (HUAC), and investigations conducted by Senator McCarthy's Senate sub-committee, culminating in 1954 with hearings about subversion within the Army.  Both committees were provided information by the Federal Bureau of Investigation (FBI) under Director J. Edgar Hoover.  In addition to these investigations, several high profile Americans were smeared by McCarthyism, including General George C. Marshall, Army Chief of Staff during WWII and chief architect of the Marshall Plan, and Dean Acheson, President Truman's Secretary of State and chief architect of American foreign policy during the early stages of the Cold War.  McCarthyism, now discredited by all but the most rabid right-wingers, caused enormous conflict within American society.
