John Kennedy actually said...

"And I hope in this way to give some slight indication of how grateful I am to all of you for making us feel so much at home."

"When they see you they see the United States."

"I hope that in all your work, and wherever you go, in all your contacts, that you will try as much as possible to associate yourselves with the well-being of all the people of Colombia."

"We believe in freedom--in the United States and in Colombia."
