In London last week, I met a Nigerian man who succinctly expressed the reaction of much of the world to America these days. “Your country has gone crazy,” he said, with a mixture of outrage and amusement. “I’m from Africa. I know crazy, but I didn’t ever think I would see this in America!”

A sadder sentiment came from a young Irish woman I met in Dublin who went to Columbia University, founded a social enterprise, and has lived in New York for nine years. “I’ve come to recognize that, as a European, I have very different values than America these days,” she said. “I realized that I have to come back to Europe, somewhere in Europe, to live and raise a family.”

The world has gone through bouts of anti-Americanism before. But this one feels very different. First, there is the sheer shock at what is going on, the bizarre candidacy of Donald Trump, which has been followed by an utterly chaotic presidency. The chaos is at such a fever pitch that one stalwart Republican, Karl Rove, described the president this week as “vindictive, impulsive and shortsighted” and his public shaming of Attorney General Jeff Sessions as “unfair, unjustified, unseemly and stupid.” Kenneth Starr, the one-time grand inquisitor of Bill Clinton, went further, calling Trump’s recent treatment of Sessions “one of the most outrageous — and profoundly misguided — courses of presidential conduct I have witnessed in five decades in and around the nation’s capital.”

But there is another aspect to the decline in America’s reputation. According to a recent Pew Research Center survey of 37 countries, people around the world increasingly believe that they can make do without America. Trump’s presidency has made the U.S. something worse than just feared or derided. It is becoming irrelevant.

The most fascinating finding of the Pew survey was not that Trump is deeply unpopular (22 percent have confidence in him, compared with 64 percent who had confidence in Barack Obama at the end of his presidency). That was to be expected — but there are now alternatives. On the question of confidence in various leaders to do the right thing regarding world affairs, China’s Xi Jinping and Russia’s Vladimir Putin got slightly higher marks than Trump. But German Chancellor Angela Merkel got almost twice as much support as Trump.

Trump has managed to do something that fear of Putin could not. He has unified Europe. Facing the challenges of Trump, Brexit and populism, a funny thing has happened on the continent. Support for Europe among its residents has risen and plans for deeper European integration are under way. If the Trump administration proceeds as it has promised and initiates protectionist measures against Europe, the continent’s resolve will only strengthen. Under the combined leadership of Merkel and new French President Emmanuel Macron, Europe will adopt a more activist global agenda. Its economy has rebounded and is now growing as fast as that of the United States.

To America’s north, Canada’s foreign minister recently spoke out, in a friendly and measured way, noting that the United States has clearly signaled that it is no longer willing to bear the burdens of global leadership To America’s south, Mexico has abandoned any plans for cooperation with the Trump administration. Trump’s approval rating in Mexico is 5 percent, his lowest in the world.

The most dismaying of Pew’s findings is that the drop in regard for America goes well beyond Trump. Sixty-four percent of the people surveyed expressed a favorable view of America at the end of the Obama presidency. That has fallen to 49 percent now.

In 2008, I wrote a book about the emerging “Post-American World,” which was, I noted at the start, not about the decline of America but rather the rise of the rest. Amid the parochialism, ineptitude and sheer disarray of the Trump presidency, the post-American world is coming to fruition much faster than I ever expected.
