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 going to have to meet the problems we face here at home if we are going to successfully convey an image of vitality and strength abroad"

"We cannot possibly afford not to make a maximum effort to get fresh water from salt water, if this State and the country is going to move ahead."

"This contest is not merely between the Vice President and myself."
