America isn’t just a piece of remarkably fertile real estate between two great oceans. It is also a state of mind.

Even when America has done wrong things (think racism) or stupid things (think Prohibition), it has still shone brightly to the world as the citadel of free expression, abundant opportunity, and a place where laws are obeyed.

When I was a teen in a British colony in Africa, long before I imagined I would spend most of my life in America, I met a man who had seen the promised land. He wasn’t a native-born American or even a citizen, but he had lived in “the States.”

I badgered this man with questions about everything, but mostly things derived from books and movies: Could ordinary people really drive Cadillacs?  As a British writer later said, were taxis in New York “great yellow projectiles”? Did they really have universities where you could study anything, like ice cream manufacturing? Did American policemen actually carry guns?

Our adulation of America was fed by its products. They were everywhere the best. American pickup trucks were the gold standard of light trucks, and American cars — so big — fascinated, although they weren’t ubiquitous like the trucks. Brands such as Frigidaire and General Electric meant reliability, quality and evidence that Americans did things better.

No one thought the streets in the United States were paved with gold, but they did believe they were paved with possibility.

There was criticism, like that of the alleged American hold on the price of gold or the fear of nuclear war. The “shining city upon a hill” idea was paramount long before President Ronald Reagan said it.

And it has been so for the world since the end of World War II. For 80 years, the United States has led the world; even when it spread its mistakes, like the Vietnam War, it led.

America was the bulwark of the liberal democracies — a grouping of European nations, Canada, Australia and much of Asia — that shared many values and outlooks. Call it what it is, or was, Western Civilization, based on decency, informed by Christianity, and shaped by tradition and common expectation.

Central to this was America; central with ideas, with wealth, with technological leadership and, above all, with decency. Now, all of this may be in the past.

This structure has been shaken in less than three months of President Trump’s second administration. It is near breaking point.

This may be the end of days for the Western Alliance, led by America in the ways of democracy and free trade.

Writing in the British monthly magazine Prospect, Andrew Adonis, a peer who sits in the House of Lords as Baron Adonis, states: “Trump doesn’t believe in democracy, just in winning at all costs. He doesn’t believe in an international order based on respect for human rights. He is an authoritarian, lawless plutocrat who admires similar characters at home and abroad.”

Additionally, Adonis says in his article that, unlike the first Trump term, the checks and balances have weakened: “The Republican Party has become a cipher. The Democrats are shell-shocked and demoralized. The courts, the military and Congress are browbeaten, packed with Trump supporters or otherwise compliant.”

I find it hard to argue with this assessment. Why would Trump persist with a tariff regime that was proven not to work with the Smoot-Hawley Tariff Act of 1930, which triggered the Great Depression? Why would he rile up Canada by threatening its independence? Why would he reopen, without a good reason, the issue of the control of the Panama Canal?

Why is he destroying the civil service in thought-free ways? Why is he going after the constitutional freedom of the press and the rights enshrined over millennia for lawyers to represent those who need them regardless of politics? Why is he leading us into a recession: the Trump Slump?

Either the president has no coherent plans, or those plans are devious and not to be shared with the people.

I believe that he enjoys power and testing its limits, that he has no knowledge base and so relies on hearsay to formulate policy. In the end, he may be listed along with Roman emperors who ran amok like Nero and Caligula.

The Western Alliance is at stake, and America is giving away its global leadership. When trust is lost, it is gone forever.
