"I want to tell you about a new step forward that we are taking with the Peace Corps, which is another form of responsibility."

"There is nothing to be gained from rattling our rockets or bluffing with our bombs, because we know, and our adversaries know, that we have the might."

"Too often too many Americans conclude that our country has completed its course."

"President Kennedy returned from Salt Lake City knowing, as he had not known before, that the people of America supported his efforts to make this world safer for all mankind."
