"The fifth area and the most important of increasing strength is the ability of the American fighting man. However impressive or ingenious, our weapons can be no better than the men who man them. The complexities of modern weapons require men of high skill. The complexities of modern warfare require men of great knowledge. The complexities of the modern world require men of broad outlook. Today 52 percent of our enlisted men are under 25 and are high school graduates, compared with 39 percent in the country as a whole who are high school graduates. Sixty-five percent of our commissioned officers are college graduates today, compared with 7 percent in the Nation. Twenty-five thousand officers hold graduate degrees and thousands more are studying for such degrees. In encampments across the world millions of men and women have chosen to serve with low pay and high hazard, with deep devotion and silent sacrifice, so that their fellow Americans might enjoy the rich legacy of liberty. They stand the hard vigil that we may pursue the high vision of flourishing freedom in a world at peace. These are the sources of the strength we build, knowing, in the words of the Bible, "When the strong man armed keepeth his palace, his goods are in peace." The necessities of our strength are as varied as the nature of our dangers. The response must suit the threat. Those who would answer every problem with nuclear weapons display not bravery but bravado, not wisdom but a wanton disregard for the survival of the world and the future of the race."
