John Kennedy actually said...

"A good many of our sons have fought there, lived there, in war and in peace."

"It gives me pleasure to have this opportunity of assuring Your Majesty that while I remain head of this nation I shall not cease to promote every measure that may contribute to the friendship and harm..."

"For all these reasons we are particularly glad to welcome you here at the present time."

"It is a high honor to welcome you once again to the United States."
