You want a feeling of dire straits in the greatest nation on Earth?

This 11-minute video ought to remind us all that we have a resilient nation, with a government cobbled together by a document that is as stout as ever.

I mention this because of those who insist we are about to enter an “unprecedented” era of crisis with the inauguration of Donald J. Trump as president of the United States.

Not so.

On Aug. 8, 1974, the nation watched one president resign and another one take office.

Gerald R. Ford ascended to the presidency after being appointed vice president less than a year earlier; the man he replaced as VP had pleaded no contest to corruption charges. Before that he was a congressman from Grand Rapids, Mich., whose No. 1 ambition was to become speaker of the U.S. House of Representatives.

Fate would steer Gerald Ford down an entirely different path.

As president, he told us that “our long national nightmare is over.” Richard Nixon was flying off to private life in California as President Ford took the reins of power.

And as the new president told us, “Our Constitution works.”

Indeed it does.

I harbor deep reservations and concern about whether the new president is up to the job he is about to assume.

However, I take comfort in the words that an earlier president, Gerald Ford, delivered as we sought to recover from a constitutional crisis the likes of which the nation had never before endured.

We certainly did recover. Whatever missteps the new president makes as he begins his term, I remain confident that our Constitution will continue to work just as our founders intended.

You have to keep the faith.
