Donald Trump promised to be America’s dealmaker in chief.

“We need a leader that wrote ‘The Art of the Deal,’ ” he said in the speech announcing his candidacy. “I’m a negotiator. I’ve done very well over the years, through negotiation,” he said during a Republican debate. “That’s what I do, is deals,” he said in May. “I know deals, I think, better than anybody knows deals.”

But so far, Trump has made no deals at all and the ones he thinks he’s made have unraveled.

He has no deal with North Korea. Following his June 12 summit with Kim Jong-un, Trump declared on Twitter that “there is no longer a nuclear threat” from North Korea.

In fact, recent satellite images show that North Korea has made upgrades to a nuclear facility. It also appears to be finalizing the expansion of a ballistic missile manufacturing site.

Instead of surrendering its nuclear stockpile, American intelligence said North Korea is considering ways to conceal it at secret production facilities.

As if to drive home the point that there’s been no deal, just after Secretary of State Mike Pompeo went to Pyongyang, North Korea, to start filling in the “nitty-gritty details” of Jong-un’s vague commitment, North Korea accused the Trump administration of pushing a unilateral and gangster-like demand for denuclearization, calling it deeply regrettable.

Trump apologists said the supposed deal with North Korea will take time.

Maybe, but Jong-un got everything he wanted from the summit: an American president appearing to grant North Korea coequal status and cancellation of joint military exercises with South Korea, without conceding a thing on weapons and missile programs.

Trump has no trade deals either. Instead, he’s launched simultaneous trade wars with Europe, China, Canada and Mexico.

After slapping tariffs on $34 billion of Chinese imports, China has retaliated with tariffs on $34 billion of American exports. Trump is now threatening tariffs on nearly everything China exports to the United States as well as a clampdown on Chinese investment here.

After Trump raised tariffs on steel and aluminum from Canada, Mexico and the European Union, they also retaliated. They promise further retaliation if Trump acts on his threat to place a 20% tariff on cars and car parts imported from Europe.

Are these Trump’s negotiating tactics? “Every country is calling every day, saying ‘Let’s make a deal, let’s make a deal,’ ” he boasted earlier this month.

That’s doubtful. Trump’s actions have poisoned relations to such an extent that instead of joining the United States to push China to open its markets, our trading partners, including China, are starting to join together to stop Trump from doing worse damage.

Meanwhile, talks to revise the North American Free Trade Agreement with Mexico and Canada are dead, partly because Trump’s bullying has generated so much animosity across our two neighbors’ borders.

Trump has no deal on Iran, either. No deal on Syria. No deal on the Qatar blockade. No deal on Israel and the Palestinians.

Trump will soon meet with Vladimir Putin, but with no apparent agenda.

Over the past few weeks, Trump has given away his bargaining leverage with Putin anyway. He’s called for Russia to be readmitted to the Group of 7 industrial powers, suggested it has a legitimate claim to Crimea because a lot of Russian-language speakers live there and expressed more doubts about whether Moscow, Russia, meddled in the 2016 presidential election.

Trump has no deal on climate change. He simply pulled out of the Paris climate accord.

There is no deal with the Group of 7 leading economic powers. Trump merely refused to sign the communique his own team had agreed to and no deal with North Atlantic Treaty Organization countries on increasing their military spending.

“No deal” also describes Trump’s relations with the Republican-majority Congress.

He got no deal on replacing the Affordable Care Act so Trump is quietly repealing it administratively. At least 5 million people will lose coverage.

There is no deal on gun control. After the Parkland, Fla., school shooting, Trump promised to tighten background checks for gun buyers and said he’d consider raising the age for buying certain types of guns. He subsequently gave up, bowing to the National Rifle Association.

There is no deal on Deferred Action for Childhood Arrivals or immigration, despite Trump’s promises and no budget deal, despite his assertions.

Even the tax deal wasn’t really Trump’s. It was a deal between the Republican Senate and Republican House, with Trump bloviating from the sidelines.

One of the biggest cons from the biggest con man to occupy the Oval Office is that he’s a dealmaker.

He’s not. After a year and a half of this, it’s clear that all he really knows is how to bully friends, stage photo ops with enemies and claim victory.
