How did the cold war further the career of Senator Joseph McCarthy How did his career end?

Senator Joseph McCarthy's career was significantly advanced by the Cold War climate of fear and suspicion, as he capitalized on anti-communist sentiment to launch high-profile investigations and make sensational claims about communist infiltration in the U.S. government. His aggressive tactics and rhetoric gained him significant media attention and popularity among Americans who feared communism. However, his career ended in disgrace after the televised Army-McCarthy hearings in 1954, where his aggressive methods were publicly scrutinized, leading to a loss of support and eventual censure by the Senate. By the late 1950s, McCarthy's influence had waned, and he died in relative obscurity in 1957.
