“But our great security lies, I think, in our growing strength”

1963, Remarks Prepared for Delivery at the Trade Mart in Dallas
Context: Our security and strength, in the last analysis, directly depend on the security and strength of others, and that is why our military and economic assistance plays such a key role in enabling those who live on the periphery of the Communist world to maintain their independence of choice. Our assistance to these nations can be painful, risky and costly, as is true in Southeast Asia today. But we dare not weary of the task. For our assistance makes possible the stationing of 3-5 million allied troops along the Communist frontier at one-tenth the cost of maintaining a comparable number of American soldiers.

Context: Our strength grows out of our weakness. The indignation which arms itself with secret forces does not awaken until we are pricked and stung and sorely assailed. A great man is always willing to be little. Whilst he sits on the cushion of advantages, he goes to sleep. When he is pushed, tormented, defeated, he has a chance to learn something; he has been put on his wits, on his manhood; he has gained facts; learns his ignorance; is cured of the insanity of conceit; has got moderation and real skill. The wise man throws himself on the side of his assailants. It is more his interest than it is theirs to find his weak point. The wound cicatrizes and falls off from him like a dead skin, and when they would triumph, lo! he has passed on invulnerable. Blame is safer than praise. I hate to be defended in a newspaper. As long as all that is said is said against me, I feel a certain assurance of success. But as soon as honeyed words of praise are spoken for me, I feel as one that lies unprotected before his enemies. In general, every evil to which we do not succumb is a benefactor.

2016, DNC Address (July 2016)
Context: America is already great. America is already strong. And I promise you, our strength, our greatness, does not depend on Donald Trump. In fact, it doesn’t depend on any one person. And that, in the end, may be the biggest difference in this election — the meaning of our democracy.
Ronald Reagan called America “a shining city on a hill.” Donald Trump calls it “a divided crime scene” that only he can fix. It doesn’t matter to him that illegal immigration and the crime rate are as low as they’ve been in decades — (applause) — because he’s not actually offering any real solutions to those issues. He’s just offering slogans, and he’s offering fear. He’s betting that if he scares enough people, he might score just enough votes to win this election.
And that's another bet that Donald Trump will lose. And the reason he'll lose it is because he’s selling the American people short. We're not a fragile people. We're not a frightful people. Our power doesn’t come from some self-declared savior promising that he alone can restore order as long as we do things his way. We don’t look to be ruled. Our power comes from those immortal declarations first put to paper right here in Philadelphia all those years ago: We hold these truths to be self-evident, that all men are created equal; that We the People, can form a more perfect union.
That's who we are. That’s our birthright — the capacity to shape our own destiny.
