Nel 1950 il Senatore McCarthy si impose all'attenzione della politica nazionale con un discorso rivolto al Dipartimento di Stato in cui pronunciò tra le altre queste parole:
Today we are engaged in a final, all-out battle between communistic atheism and Christianity. The modern champions of communism have selected this as the time. And, ladies and gentlemen, the chips are down -- they are truly down. [.] Ladies and gentlemen, can there be anyone here tonight who is so blind as to say that the war is not on? Can there be anyone who fails to realize that the communist world has said, "The time is now" -- that this is the time for the showdown between the democratic Christian world and the communist atheistic world? Unless we face this fact, we shall pay the price that must be paid by those who wait too long .
