How does John F. Kennedy employ rhetorical elements of ethos and pathos to persuade his audience? Read the text below from John F. Kennedy's inaugural address: "We dare not forget today that we are the heirs of that first revolution. Let the word go forth from this time and place, to friends and foe alike, that the torch has been passed to a new generation of Americans-born in this century, tempered by war, disciplined by hard and bitter peace, proud of our ancient heritage-and unwilling to witness or permit the slow undoing of those human rights to which we are committed today at home and around the world. Let every nation know, whether it wishes us well or ill, that we shall pay any price, bear by burden, meet any hardship, support any friend, oppose any foe, in order to assure the survival and the success of liberty."
John F. Kennedy mixes ethos and pathos in the quote you cite in many ways. He uses "ethos" by saying "we" instead of "you" or "I". This makes us seem like we share the same spirit and are united to "assure [...] the success of liberty." As for pathos, we could say that by evoking past wars and "hard and bitter peace," Kennedy makes us feel compassion and gratitude for those who fought for the prosperity that many now have.
