How did the impact of new communist regime in china and the outbreak of the Korean war contribute to the rise of Joseph McCarthy?

The establishment of the communist regime in China in 1949 heightened fears of communist expansion in the U.S., contributing to a climate of paranoia about domestic infiltration. The outbreak of the Korean War in 1950 further intensified these fears, as it was viewed as a direct confrontation with communism. Amidst this backdrop, Senator Joseph McCarthy capitalized on public anxieties by alleging widespread communist infiltration in the U.S. government and society, leading to his rise as a prominent figure in the anti-communist movement. His tactics and rhetoric resonated with a populace already on edge, fueling the Red Scare of the early 1950s.
