You thought Trump couldn't go any lower. Guess what?

President Donald Trump disgraced America again on Tuesday.

That’s business as usual, in most contexts. But this time Trump projected his psychosis beyond the customary bounds of American politics.

Trump stood before the United Nations General Assembly and delivered a rant filled with insults and lies that might go down in history as the vilest of its kind.

Presumably speaking for all of us Americans, Trump told the entire world to f––– off.

Among the most vile lowlights of Trump’s tantrum:

• He dismissed climate change as a “con job,” mocking decades of scientific consensus in front of world leaders who have committed themselves to fighting rising seas and burning forests.
• He framed immigration as a global poison, attacking nations that take in refugees while offering no solutions — just fear, contempt and seething xenophobia.
• He claimed Christianity is the most persecuted religion on Earth, an inflammatory lie intended to stoke division and grievance while pandering to his White Nationalist base.
• He vomited falsehoods that he had presumably “resolved” seven major conflicts — including Israel-Iran and India-Pakistan, rewriting reality while of course offering no proof since none exists and drawing eye-rolls, not applause.
• He told U.N. diplomats their countries are “going to hell” for permitting too much immigration, then basked in the moment like he was inflaming a rally crowd, not representing all Americans at a global forum.

Here’s how the Wall Street Journal news report characterized the speech:

In an hour-long speech filled with grievances about ongoing wars, windmills and malfunctioning escalators, it was Trump’s attacks against what he called a “double-tailed monster” that rang loudest in the ornate General Assembly room.

“Immigration and the high cost of so-called green, renewable energy is destroying a large part of the free world and a large part of our planet,” he said.

“Countries that cherish freedom are fading fast because of their policies on these two subjects. Both immigration and their suicidal energy ideas will be the death of Western Europe.”

Immigration in particular was ruining other nations, Trump insisted: “Your countries are going to hell.”

(Now, if you’re wondering about the escalator references, Trump was whining like a toddler about how an escalator in the UN building had stopped for a moment, briefly stranding him and First Lady Melania Trump. All our hearts go out to Melania.)

Certainly, there’s nothing wrong with a U.S. president calling out the UN for perceived ineffectiveness. Many Americans share that concern — and while some of us would rather see constructive, adult engagement to improve the UN’s efforts, that would remain perfectly within the bounds of propriety.

But that’s not what Trump did yesterday. He put on world display a level of hatred and boorishness — and a cringeworthy lack of gravitas — that certainly had diplomats the world over shaking their heads. Even beyond what they have come to expect.

Two days before the UN speech, Trump delivered one just as toxic at the memorial service for slain conservative icon Charlie Kirk. There, he proclaimed, “I hate my opponent, I don’t wish him well.”

That, of course, was a message to the sizable majority of Americans — at least 60 percent and counting — who disapprove of Trump today. Without apology, he let hundreds of millions of Americans know of his hatred for them.

But Trump didn’t just stop with us today. He also let it be known that he hates the world.

“Your countries are going to hell!” Trump raged.

That’s the only way he’d ever get to know them better.
