Answer: In the third paragraph of his inaugural address, Kennedy says:
"Let every nation know, whether it wishes us well or ill, that we shall pay any price, bear any burden, meet any hardship, support any friend, oppose any foe to assure the survival and the success of liberty. This much we pledge—and more."
Here, Kennedy is calling on Americans to make an effort to support and defend liberty, not only for themselves but for people around the world. He suggests that this may require sacrifice and hardship, but it is necessary to ensure the survival and success of freedom.
In the fifth paragraph, Kennedy states:
"Finally, whether you are citizens of America or citizens of the world, ask of us the same high standards of strength and sacrifice which we ask of you. With a good conscience our only sure reward, with history the final judge of our deeds, let us go forth to lead the land we love, asking His blessing and His help, but knowing that here on earth God's work must truly be our own."
Here, Kennedy is again emphasizing the need for effort and sacrifice. He asks Americans to hold themselves to the same high standards that they ask of others, and to work together to lead their country and advance the cause of freedom. He suggests that this work is not just a political or economic task, but a moral and spiritual one that requires individuals to take responsibility for their actions and work towards a common goal.
