[The big debates, distilled. This guide will put in context what people are saying about the pressing issues of the week. Sign up for our new newsletter, Debatable.]

But, beneath the outward sense of hope and duty that I witnessed at these two events, there was an underlying current of frustration, humiliation, anger and fear that echoed across the sidelines. The America that they believed in was under attack, not from without, but from within.

These men and women, of all political persuasions, have seen the assaults on our institutions: on the intelligence and law enforcement community, the State Department and the press. They have seen our leaders stand beside despots and strongmen, preferring their government narrative to our own. They have seen us abandon our allies and have heard the shouts of betrayal from the battlefield. As I stood on the parade field at Fort Bragg, one retired four-star general, grabbed my arm, shook me and shouted, “I don’t like the Democrats, but Trump is destroying the Republic!”

Those words echoed with me throughout the week. It is easy to destroy an organization if you have no appreciation for what makes that organization great. We are not the most powerful nation in the world because of our aircraft carriers, our economy, or our seat at the United Nations Security Council. We are the most powerful nation in the world because we try to be the good guys. We are the most powerful nation in the world because our ideals of universal freedom and equality have been backed up by our belief that we were champions of justice, the protectors of the less fortunate.

But, if we don’t care about our values, if we don’t care about duty and honor, if we don’t help the weak and stand up against oppression and injustice — what will happen to the Kurds, the Iraqis, the Afghans, the Syrians, the Rohingyas, the South Sudanese and the millions of people under the boot of tyranny or left abandoned by their failing states?

If our promises are meaningless, how will our allies ever trust us? If we can’t have faith in our nation’s principles, why would the men and women of this nation join the military? And if they don’t join, who will protect us? If we are not the champions of the good and the right, then who will follow us? And if no one follows us — where will the world end up?

President Trump seems to believe that these qualities are unimportant or show weakness. He is wrong. These are the virtues that have sustained this nation for the past 243 years. If we hope to continue to lead the world and inspire a new generation of young men and women to our cause, then we must embrace these values now more than ever.
