Trump said. “Frankly, that Iran deal is an embarrassment to the United States

Leaders from around the globe took the lectern at the United Nations General Assembly on Tuesday — a particularly big moment for President Trump, who addressed the gathering for the first time.

In his speech, Mr. Trump vowed to “totally destroy” North Korea if it threatened the United States or its allies. “If the righteous many don’t confront the wicked few, then evil will triumph,” he said.

He also called Iran a “rogue nation” and said the United States was “prepared to take further action” on Venezuela.

President Emmanuel Macron of France countered those remarks in his own address, saying that the nuclear deal with Iran was “essential for peace” and that his country would “not close any door to dialogue” with North Korea.

Prime Minister Benjamin Netanyahu of Israel agreed with Mr. Trump’s assessment of Iran, however, saying, “Imagine the danger of hundreds of nuclear weapons in the reins of a vast Iranian empire, with the missiles to deliver them anywhere on Earth.”

Trump threatens to ‘totally destroy’ North Korea.

If the United States is forced to defend itself or its allies, “we will have no choice but to totally destroy North Korea,” President Trump said in his address to the General Assembly.

He denounced North Korea and its leader, Kim Jong-un, saying the nation “threatens the entire world with unthinkable loss of life” as a result of its nuclear weapons program.

“If the righteous many don’t confront the wicked few, then evil will triumph,” Mr. Trump said.

Mr. Trump emphasized that it was against the interest of the entire world for North Korea — which he called a “band of criminals” — to obtain missiles and nuclear weapons.

“Rocket man is on a suicide mission for himself,” he said of Mr. Kim.

Mr. Trump accused Mr. Kim of overseeing a regime that has starved its people, brutalized an imprisoned American college student who was returned home in a coma, and assassinated Mr. Kim’s older brother, a potential rival, with poison chemicals.

“If this is not twisted enough, now North Korea’s reckless pursuit of missiles and nuclear weapons threatens the entire world,” Mr. Trump said.

While he thanked Russia and China for supporting recent United Nations sanctions on North Korea, Mr. Trump also took an indirect swipe at them for continuing to do business with Mr. Kim.

“It is an outrage that some nations would not only trade with such a regime, but would arm, supply and financially support a country that imperils the world,” Mr. Trump said.

The president said that America would act alone if needed. He emphasized an “America first” agenda, and said that while the United States would “forever be a great friend to the world and especially to its allies,” his primary responsibility was to Americans.

“As president, I will always put America first, just like you as the leaders of your countries will always — and should always — put your countries first,” he said.

After condemning North Korea, Mr. Trump pivoted to the next “rogue nation” — Iran.

He called the Iran nuclear deal “an embarrassment” that is “one of the worst and most one-sided transactions the United States has ever entered into.”

Mr. Trump has long portrayed Iran as a sponsor of terrorism and has suggested that the United States may abandon the 2015 deal negotiated by the Obama administration and five other major powers that limited Iran’s nuclear activities. So far Mr. Trump has grudgingly accepted the nuclear agreement despite having described it as a disgrace.

“It is time for the entire world to join us in demanding that Iran’s government end its pursuit of death and destruction,” he said.

The world’s nuclear inspectors recently declared that they had found no evidence that Iran is breaching the agreement. A meeting of the parties that negotiated the deal with Iran — Britain, China, France, Germany, Russia and the United States — will take place on the sidelines of the General Assembly on Wednesday.

“The Iranian government masks a corrupt dictatorship behind the false guise of a democracy,” Mr. Trump told the United Nations on Tuesday. “It has turned a wealthy country with a rich history and culture into an economically depleted rogue state whose exports are violence, bloodshed and chaos.”

Mr. Trump also called on the Iranian authorities to free the American citizens being held in Iranian prisons. At least four are incarcerated, and a fifth has been missing for a decade.

Netanyahu echoes Trump on the Iran nuclear deal.

Prime Minister Benjamin Netanyahu of Israel, who applauded at Mr. Trump’s criticism of Iran, heaped more praise on the American leader when it was Mr. Netanyahu’s turn to speak a few hours later, thanking the administration for its “unequivocal support.”

Mr. Netanyahu said Mr. Trump had “rightly called the nuclear deal with Iran an embarrassment,” and was especially critical of the so-called sunset clauses in the agreement that will allow Iran to eventually increase uranium enrichment.

“In the last few months, we’ve all seen how dangerous even a few nuclear weapons can be in the hands of a small rogue regime,” Mr. Netanyahu said in reference to North Korea. “Now imagine the danger of hundreds of nuclear weapons in the reins of a vast Iranian empire, with the missiles to deliver them anywhere on Earth.”

Firing back at Ayatollah Ali Khamenei and other Iranian leaders who have threatened Israel’s destruction, Mr. Netanyahu said they “put themselves in mortal peril.”

Disarmament experts have said that they expect Iran to abide by the nuclear agreement regardless of Mr. Trump’s intentions. Iran has repeatedly said that it will never acquire nuclear weapons.

President Emmanuel Macron of France took sharp exception to President Trump’s remarks at the General Assembly.

He challenged Mr. Trump’s dismissal of the Iran nuclear agreement, defending it as “solid, robust and verifiable.” The French leader said that renouncing the deal with Iran would be a “grave error,” calling the agreement “essential for peace.”

Britain, China, Germany and Russia also hold that view, which could isolate the United States should Mr. Trump carry out his threat to quit the Iran accord.

Mr. Macron seconded Mr. Trump’s assertion that North Korea’s nuclear belligerence is dangerous and unacceptable. But while Mr. Trump vowed to “totally destroy” North Korea if it threatened the United States or its allies, Mr. Macron said diplomatic pressure was the best solution.

“France rejects escalation and will not close any door to dialogue,” he said.

He also addressed a big issue that Mr. Trump conspicuously omitted: climate change.

“The planet will not negotiate with us,” Mr. Macron said in defending the Paris climate accord, which Mr. Trump has renounced.

“I fully respect decision of the United States, but the door will always be open,” Mr. Macron said, alluding to the possibility that the United States might someday rejoin the pact. “However, we will continue with all governments, we will continue to implement the Paris agreement.”

In what appeared to be a swipe at Mr. Trump’s embrace of oil and coal, Mr. Macron said that France’s position “may not be pleasing to those who believe the future is looking to the past.”

Trump is ‘prepared to take action’ on Venezuela.

Later in his speech, Mr. Trump turned his attention to the Americas.

He excoriated the leadership of President Nicolás Maduro of Venezuela, who has turned increasingly repressive as the country’s economy has collapsed.

Mr. Trump declared that the United States was “prepared to take further action if the government of Venezuela persists on its path to impose authoritarian rule on the Venezuelan people.” He said Mr. Maduro’s government had “destroyed a prosperous nation by imposing a failed ideology that has produced poverty and misery everywhere it has been tried.”

“This situation is completely unacceptable, and we cannot stand by and watch as a responsible neighbor and friend,” Mr. Trump said.

Mr. Trump’s government has imposed economic sanctions on Mr. Maduro’s government but has not specified how it would exert further pressure. Last month, he caused a backlash among Latin American leaders by suggesting that he could order American military forces to intervene in Venezuela.

Venezuela responded on Tuesday by criticizing what it called Mr. Trump’s “fatal obsession with Venezuela, a product of his white supremacist ideas.”

“We’re ready to continue, on the political and diplomatic level, and on any level necessary, defeating the disastrous aggressions of the U.S. government,” the country’s government said in a statement.

Mr. Trump in his address on Tuesday also vowed to continue pressuring what he called the “corrupt, destabilizing regime” in Cuba.

“We will not lift sanctions on the Cuban government until it makes fundamental reforms,” he said.

Did Trump breach U.N. Charter in his warning to Kim Jong-un?

President Trump’s threat to “totally destroy” North Korea if it threatens the United States caused a debate among scholars of international law about whether he had violated a tenet of the United Nations Charter.

Article 2(4) of the Charter says countries should “refrain in their international relations from the threat or use of force” against another country. The only exceptions to that are if it is sanctioned by the Security Council or if it is an act of self-defense.

In this instance, there is no such authorization from the Security Council. And so the question is: Was Mr. Trump justified on the basis of self-defense?

John B. Bellinger, who served as a legal adviser in the administration of George W. Bush, said that despite his “colorful” choice of words, Mr. Trump invoked the self-defense argument explicitly.

“His threat to destroy North Korea did not violate the U.N. Charter because he said that the United States would use force only ‘if the United States is forced to defend itself or its allies,’” Mr. Bellinger said by email. “The Charter specifically allows a U.N. member to use force in self-defense.”

Mark Ellis, executive director of the International Bar Association, said the International Court of Justice had stipulated that countries can act unilaterally if facing an armed attack, but there is a lack of clarity on what armed attack means.

Kevin Jon Heller, a law professor at the University of London, said he believed Mr. Trump had overstepped.

“The problem is that self-defense must always be proportionate to the armed attack, and Trump clearly threatened disproportionate force,” Mr. Heller argued. “Had he said a nuclear attack would require wiping North Korea off the face of the earth, that might have been a lawful threat. But he did not qualify the threat in any way; on the contrary, he suggested North Korea would have to be destroyed in response to any armed attack on the U.S. or its allies. That is an unlawful threat that violates Art. 2(4).” —SOMINI SENGUPTA

Trump gets rocket of his own — in salad form.

First he derided North Korea’s leader as “rocket man.” Then President Trump was served rocket salad for lunch.

Wild rocket actually. The menu described it as a salad that also combined romaine lettuce, chanterelle mushrooms and haricot verts, grilled stone fruit and “smothered in white balsamic & truffle vinaigrette.”

It was paired with a 2016 Sancerre.

The president sat at the head table with Secretary General António Guterres, whose speech earlier at the General Assembly was a sharp counterpoint to Mr. Trump’s bellicose, nationalist remarks in the hall.

Lunch for world leaders was served in the second-floor North Delegates Lounge, where on most days diplomats drink espresso out of paper cups.

Mr. Trump gave a toast — barely sipping because he does not drink alcohol — to the “great, great potential” of the United Nations, telling those assembled there, “You’re going to do things that will be epic.”

On the wall behind the podium was a large tapestry of the Great Wall of China — a gift to the United Nations from Beijing.

Also seated at the head table with him were the presidents of Japan, South Korea and Liberia, along with the king of Jordan.

The main course was beef Wagyu tenderloin. Dessert included a chocolate mousse and raspberries, accompanied by a 40-year-old Port from the secretary general’s home country, Portugal.

How much jet fuel was spent on bringing this lunch to the table was unclear.
