Joseph Kennedy had befriended McCarthy because he found him to be a likable fellow Irish-Catholic who had all the right ideas on the domestic communist menace. These warm feelings were quickly transferred to the entire Kennedy family. JFK liked the fact that McCarthy went after the "elites" in the State Department whom JFK regarded with contempt. (13) Even before McCarthy made accusations against the State Department of subversion, JFK had already aligned himself with the militant anti-communists who blamed the Truman State Department for the "loss" of China. So JFK declared on the House floor in January 1949.
"The responsibility for the failure of our foreign policy in the Far East rests squarely with the White House and the Department of State." (14)
Kennedy later spoke with great affection for General Douglas MacArthur.

"General MacArthur was the single greatest bullwork of American defense in the Pacific against the brutality and scourge of murdering Communism. The will to stop and reverse the tide of Communist aggression was more within him than shamefully was not with the President."
