John Kennedy actually said...

"I can assure you that this is a young and vital country, but what we do here in our own country affects the security of the United States around the world."

"I think we are ready to move."

"I don't run for the office of the Presidency promising you that if I am elected that life will be easy and the problems all solved"

"If it is going to move in the direction of freedom, if it is going to move in the direction of the things which we value, then the United States has to lead."
