“Today, our dominant international challenge is to restore the greatness of America, based on telling the truth, a commitment to peace, and respect for civil liberties at home and basic human rights around the world.
Truth is the foundation of our global leadership, but our credibility has been shattered and we are left increasingly isolated and vulnerable in a hostile world.
Without truth, without trust, America cannot flourish. Trust is at the very heart of our democracy, the sacred covenant between a president and the people.
When that trust is violated, the bonds that hold our republic together begin to weaken.”

1960s, Farewell address (1961)
Context: We now stand ten years past the midpoint of a century that has witnessed four major wars among great nations. Three of these involved our own country. Despite these holocausts, America is today the strongest, the most influential, and most productive nation in the world. Understandably proud of this pre-eminence, we yet realize that America's leadership and prestige depend, not merely upon our unmatched material progress, riches and military strength, but on how we use our power in the interests of world peace and human betterment.

2016, Disabled American Veterans Convention (August 2016)
Context: Our commitment to our veterans is a sacred covenant.... It is sacred because there's no more solemn request than to ask someone to risk their life, to be ready to give their life on our behalf. It's a covenant because both sides have responsibilities. Those who put on the uniform, you took an oath to protect and defend us. While the rest of us, the citizens you kept safe, we pledged to take care of you and your families when you come home. That's a sacred covenant. That's a solemn promise that we make to each other. And it is binding. And upholding it is a moral imperative.... If there’s ever a breach in the covenant, then leaders in this country have to work hard to regain trust.... And when we take care of each other and uphold that sacred covenant, there is nothing we cannot do.
