John Kennedy actually said...

"I do not want our politics colored by considerations of national security, and I do not want our national security colored by considerations of politics."

"This country cannot settle for being first, if; first, but; first, when; first, maybe."

"But that does not mean that these problems are incapable of solution."

"Let me make it very clear that this country will not be in a position of influence around the world unless we are strong here in the United States."
