US President Donald Trump began his address at the 81st UN General Assembly in New York by listing what he described as the shining achievements of his second term as president.
"We inherited a dark age of America from the previous administration, and we turned it into the golden age of America," he said, touting his record on the economy, immigration and crime.
He then moved on to Iran. "I believe we'll make a deal right after the election because it doesn't make sense for them not to," he said, referring to the US midterm elections which are coming up in early November.
Trump again said he will never allow Iran to have a nuclear weapon, to which he received brief applause.
"They were the bully of the Middle East, but they are the bully no more," Trump said of Iran.
"I call on all nations to join us in enforcing the complete economic isolation of Iran until they stop their attacks on commercial shipping, relinquish their nuclear ambitions, and cease their support of terror."
During his lengthy remarks on the subject of Iran, Trump said he had a choice to make about whether to pursue war or peace with the country.
"I have a big decision to make. Will a deal be made with Iran that lets them rebuild and create a far greater country than it ever was before?" he said.
"Or do I annihilate the Islamic Republic and do it quickly, never giving them a chance to kill and destroy people and countries again. Do I drive them into hell with no chance of survival and no hope of future greatness or generations?"
Trump then turned to Cuba, saying that the US is seeking a "fundamental change in the situation" in the country.
"It's an absolutely failed state, it's failing like never before, and it will fall," he said.
The delegation for Cuba walked out of the assembly as Trump was speaking.
Trump said Secretary of State Marco Rubio, a Cuban American, is handling negotiations.
He said the US will "not allow a haven for foreign adversaries to threaten America on our own doorstep, right at our doorstep."
Trump presented his administration's actions in Venezuela as a great victory and as a potential warning to others.
"Our actions in Venezuela are proof that the United States will no longer permit threats to America to gain a foothold anywhere in the Western Hemisphere, and if necessary, we will use our unmatched military might to secure the vital national interests of the United States," he said.
Trump attacked the International Criminal Court in vitriolic terms during his speech, describing it as a "rogue" and "out-of-control" institution.
"I call on all nations that are members of the ICC to officially resign from this rogue institution immediately," he said.
His comments come as his administration is preparing sanctions against the court that it plans to announce soon.
Based in The Hague in the Netherlands, the court prosecutes war crimes and genocide worldwide. The US has never been a member but many of its traditional allies are.
In his address, Trump said he will only encourage AI and not stifle the technology.
"We're leading now over China by a lot and everyone else. ... I'm not going to stifle growth of something that will be bigger than the industrial revolution," Trump said.
He also proposed changing the term "AI" to "super intelligence" in all US government documents.
"From this point forward, all of United States documents and hopefully the world's will be changed to use the much more accurate term super as opposed to artificial. So it's super intelligence. In other words, welcome to the new world of superintelligence.
"We will only encourage superintelligence. We're going to encourage it, not rein it in. We're going to watch it closely through the Department of Justice," Trump said.
"Now I say whoever wins AI, whoever wins super intelligence, wins," he added.
Trump and the leaders of Greenland and Denmark also signed an agreement, considered a landmark security deal.
It permits a larger US military presence on Greenland and may resolve a standoff over the strategically located and mineral-rich island.
The agreement, signed during Trump's visit to the UN General Assembly in New York, stops short of Trump's demand that the US adopt Greenland, an autonomous territory of Denmark, as a US territory to head off the growing Arctic presence of Russia and China.
But the deal does permit a greater US military presence on the icy territory, an option that emerged as Greenland leaders argued against a complete US takeover.
In his speech to the assembled world leaders at the UN before the signing ceremony, Trump said the agreement gives the US "permanent control over security and all other needs on that territory."
Trump signed the agreement along with Danish Prime Minister Mette Frederiksen and Greenland Prime Minister Jens-Frederik Nielsen in a trilateral ceremony after Trump gave his UN speech.
Frederiksen described the agreement as "a deal that can "last forever" and said it underlines the importance of the NATO alliance and respects Greenland's right to self-determination.
