Beware the influence of the military-industrial complex.

Men and women, inspired by faith in man's dignity, goaded by conviction in man's responsibility, labored that this land might be a better home for those who followed them. Because every American generation attacked its problems with fresh vigor, we have peopled a continent, subdued its prairies and wilderness, tamed its rivers and devoted its resources to the betterment of those who dwell in it.

We ... must avoid the impulse to live only for today, plundering for our own ease and convenience the precious resources of tomorrow.
