"I want to discuss with you today the status of our strength and our security because this question clearly calls for the most responsible qualities of leadership and the most enlightened products of scholarship. For this Nation's strength and security are not easily or cheaply obtained, nor are they quickly and simply explained. There are many kinds of strength and no one kind will suffice. Overwhelming nuclear strength cannot stop a guerrilla war. Formal pacts of alliance cannot stop internal subversion. Displays of material wealth cannot stop the disillusionment of diplomats subjected to discrimination. Above all, words alone are not enough. The United States is a peaceful nation. And where our strength and determination are clear, our words need merely to convey conviction, not belligerence. If we are strong, our strength will speak for itself. If we are weak, words will be of no help."

“Everything essential to the security of freedom must be done; and if that should require more men, or more taxes, or more controls, or other new powers, I shall not hesitate to ask them. I realize that no public revenue measure is welcomed by everyone. But I am certain that every American wants to pay his fair share, and not leave the burden of defending freedom entirely to those who bear arms. For we have mortgaged our very future on this defense--and we cannot fail to meet our responsibilities.”

“Third, and finally, the educated citizen has an obligation to uphold the law. This is the obligation of every citizen in a free and peaceful society — but the educated citizen has a special responsibility by the virtue of his greater understanding. For whether he has ever studied history or current events, ethics or civics, the rules of a profession or the tools of a trade, he knows that only a respect for the law makes it possible for free men to dwell together in peace and progress.”
