Only a brief time back, we were spending at the rate of only about one million dollars a year on long range ballistic missiles. In 1957 we spent more than one billion dollars on the Atlas, Titan, Thor, Jupiter, and Polaris programs alone. But I repeat, gratifying though this rate of progress is, we must still do more! Our real problem, then, is not our strength today; it is rather the vital necessity of action today to ensure our strength tomorrow.
