“I think we’re going to do things that people would be shocked at,” President Donald Trump declared on his second day in office. It was one of the few true things he said all week.

The crush of vindictive, cruel, unconstitutional and just plain bonkers orders and actions coming from the restored Trump administration in its first week makes even the worst-case predictions look conservative. But if you’re feeling knocked off-kilter by the fire hose of bad policies, well, you’re in good company. Trump himself seems downright bewildered.

On his first evening back in office, Trump invited reporters into the Oval Office, where he discussed his new decree that NATO members must spend 5 percent of their nation’s wealth on their militaries. (He perhaps is unaware that the United States spends only about 3 percent and would have to come up with another $500 billion annually to fulfill his edict.) Complaining about the “very low” military spending of Spain, Trump told his questioners: “They’re a BRICS nation, Spain. You know what a BRICS nation is? You’ll figure it out.” The 47th president then said that he would “put at least 100 percent tariff on the business they do with the United States.”

Spain, part of the European Union, is not a member of the “BRICS” bloc, short for Brazil, Russia, India, China and South Africa. But this, apparently, is news to our belligerent president. The United States might not have been in a conflict with Spain since 1898, but Trump is not one to let bygones be bygones.

Maybe he’ll “figure it out.”

The next evening brought more astounding ignorance from the chief executive. This time, he brought reporters into the Roosevelt Room to unveil a supposed $500 billion joint venture regarding artificial intelligence. But the ruse was exposed by none other than Trump sidekick Elon Musk, who proclaimed: “They don’t have the money.”

At the event, NBC News’s Peter Alexander asked Trump about why he had just pardoned D.J. Rodriguez, who shocked a police officer with a stun gun at the Capitol on Jan. 6, 2021, and later boasted that he “tazzzzed the f— out of the blue.” The judge who sentenced Rodriguez to more than 12 years called him a “one-man army of hate, attacking police.”

“Well, I don’t know,” Trump replied. “Was it a pardon?”

Alexander reiterated that it was.

“Okay. Well, we’ll take a look at everything,” Trump said, though his pardons of this and other cop-beaters are irrevocable.

Trump soon moved on to demanding that California “turn the valve” to allow more water to reach Los Angeles, where, he said, residents of Beverly Hills have been limited to 38 gallons of water per day. “When you’re a rich person, you like to take a shower. Thirty-eight gallons doesn’t last very long.”

There is no such “valve,” and no such water restrictions in Beverly Hills. But Trump skipped merrily from that error to another: Addressing a controversy that has split his staff members, he explained that he supports the H1-B visa program because it allows his properties to hire “maître d’s, wine experts, even waiters.” Thus did he apparently confuse the H1-B visa, covering those with technical expertise, with the H2-B, covering temporary workers.

Trump continued on, scolding the Biden administration for failing to negotiate a release of the hostages from Gaza “a year and a half, two years ago.” Good point! Biden should have secured the hostages’ freedom before they were taken captive on Oct. 7, 2023.

And by Thursday afternoon, the perplexed president seemed unaware that his administration was preparing to send around 10,000 troops to the southern border, as described in a U.S. Customs and Border Protection briefing document obtained by The Post.

“The southern border?” Trump replied when a reporter asked him about the plan. He then repeated an unrelated fiction he had offered earlier about offering 10,000 troops to protect the Capitol on Jan. 6, 2021.

MAGA diehards love the chaos. Others who voted for Trump might feel, not for the last time, that they were sold a bill of goods. They wanted law and order and instead got a president blessing violence against police. They wanted a crackdown on illegal immigration and instead got a president turning away law-abiding migrants who waited in line for a chance to claim asylum. They believed Trump’s promises that he would bring peace to Gaza and end the war in Ukraine in 24 hours. But now, he says that he’s “not confident” about the Gaza ceasefire (“It’s not our war”), and admits that “I don’t know” whether Russian leader Vladimir Putin wants to resolve the Ukraine conflict.

The evidence that Donald Trump was truly, madly and deeply confused was worrisome when he was a candidate. It’s all the more so now that he is wielding the mighty apparatus of the U.S. government to pursue his fantasies. This is a classic case of garbage in, garbage out — but now he is making the country a landfill for his nonsensical policies.

Oh, and as for Trump’s promise to reduce prices for Americans? He issued a vague and meaningless executive order proclaiming that agencies should “deliver emergency price relief.” Problem solved!

As Trump went on and on Wednesday night about his lust for retribution against Biden, Sean Hannity tried to interrupt: “Let me get to the economy. I’m running out of time.”

“I don’t care,” Trump replied. “This is more important.”

It’s going to be a long four years.
