John Kennedy actually said...
Because of our respect for this accomplishment, our appreciation for the very valiant struggle of your own people for a period of 20 years, and because we like to have people come to the United States--who perhaps have read about us--and see our country, see our people, talk to them, get some idea of what the great Republic stands for--for all these reasons, you are a most welcome guest, and I am confident that when you leave the United States you will have a greater understanding of the very clear desire of the people of the United States to live in peace.
