John Kennedy actually said...

"I want to express my appreciation to all of you for your welcome."

"I am glad to be here also, Mr. President, because Italy occupies a position of strategic importance, vital to the security of Europe, vital to the security of the United States."

"It is our task, I think, Mr. President, to make sure, in the interest of both of our countries, that that association remains as strong in the future as it has been in the past."

"I think the progress that we made during our discussions in coming to an agreement on the instructions of our emissaries, I think made this meeting particularly useful."
