U.S. President Donald Trump is vowing to keep using military power to advance his country's interests, including to stop what he calls "hostile foreign adversaries" from gaining influence in the Western Hemisphere.

U.S. President Donald Trump is telling the world that he will keep using military power to advance his country's interests, including stopping what he calls "hostile foreign adversaries" from gaining influence in the Western Hemisphere.

During his speech to the United Nations General Assembly on Tuesday, Trump threatened Iran with annihilation, laid claim to Venezuela's oil as the spoils of victory, and justified U.S. strikes on alleged drug traffickers in the Caribbean.

He also warned countries that more such interventions could follow.

"We have acted with decisiveness and speed to reshape the world stage and solve problems that have plagued us for far too long," said Trump.

"We're reasserting American power, including American military power, where necessary in our region and around the world, to create a safer future for all of us."

Trump's 37-minute speech to the annual gathering of world leaders only briefly touched on Russia's long-running war against Ukraine. He pleaded for an end to the conflict but offered no new initiatives toward peace.

Trump raises possibility of Iran deal — or that he could 'drive them into hell'

U.S. President Donald Trump, who spoke the United Nations on everything from artificial intelligence to Cuba's 'failed state,’ says he has a 'big decision' ahead on Iran. Trump said he believes 'we'll make a deal' but also raised the possibility he could 'annihilate the Islamic Republic' and never give them a chance to harm other nations again.

He devoted a notable portion of his speech to the Western Hemisphere. That echoes his new national security strategy, published last December before Trump ordered the mission to capture Venezuelan President Nicolás Maduro and joined Israel in launching the war against Iran.

The official strategy document, which drew praise from the Kremlin, argues for reviving the Monroe Doctrine, the 19th-century declaration of U.S. supremacy over the Western Hemisphere.

'Vicious gangs, bloodthirsty cartels'

Previous U.S. administrations have allowed much of the region to be "dominated by vicious gangs and bloodthirsty drug cartels, destabilized by uncontrolled migration and infiltrated by hostile foreign adversaries — foreign, sick, demented adversaries," said Trump.

"But not anymore," he continued.

"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 boasted about the deal that gives the U.S. control over much of Venezuela's oil productions. "To the victor belong the spoils," he declared.

The speech made clear not only the importance of the Western Hemisphere to Trump's worldview, but also his perception of the region as a potential threat, says Shannon O'Neil, a senior vice-president at the Council on Foreign Relations, a think-tank based in Washington, D.C.

The message sets the U.S. up "to assert control, if not dominance, in this hemisphere," O'Neil told reporters in an online panel discussion Tuesday.

She sees the Trump administration's approach to the governments of Latin America as "really trying to put their finger on the scale to encourage and support those that were ideologically aligned."

Canada gets a pass

The speech did not mention Canada, evidence that the U.S. president has bigger preoccupations than the trade war with his country's northern neighbour.

Trump did, however, take on its southern neighbour, calling Mexico the epicenter of drug cartel violence.

"It's unacceptable for the United States to share a 2,000-mile border with a territory controlled by enemy cartels. So Mexico must reclaim control of its soil from the enemies of humanity," he said.

Trump also said his administration is seeking "fundamental change" in Cuba.

Members of Cuba's delegation walked out after U.S. President Donald Trump called their country an 'absolutely failed state' during his speech to the United Nations General Assembly in New York.

"The communist regime is under great pressure," he said. "We'll not allow a haven for foreign adversaries to threaten America on our own doorstep."

Members of the Cuban delegation walked out of the General Assembly hall as Trump spoke.

'Do I annihilate the Islamic Republic?'

Trump also said he faces a "big decision" on Iran.

He said one option is making a deal that allows Iran to become a "far greater country" than ever before.

"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?"

That was Trump's way of laying out both a path for a negotiated solution and the consequences of not following that path, says Mara Rudman, a former U.S. deputy special envoy for the Middle East.

"Fairly clumsy is maybe the kindest word I can use," Rudman told CBC News Network shortly after the speech.

Trump was due to meet the leaders of Gulf countries on the sidelines of the General Assembly on Tuesday.

"My anticipation is that they are urging him, however quietly, to go down the path of negotiation," said Rudman, who served as a national security advisor in both the Clinton and Obama administrations.

Trump predicted that a deal with Iran will happen immediately after the U.S. midterm elections on Nov. 3.

Rudman sees that as evidence that the midterms — which polling suggests put the Republican Party at risk of losing both the U.S. House and Senate — are weighing on the president.

"I think his audience was the American people and not the Iranians or anyone else in the world, despite the fact that he was speaking at the UN," she said.

Trump also used the General Assembly podium to call fears over the risks posed by artificial intelligence a hoax and to repeat some of his long-running sharp criticisms of the United Nations, the main theme of his speech last year.

He also called the International Criminal Court a rogue organization. The court was created jointly by 125 countries in the early 2000s to prosecute war crimes and crimes against humanity. The U.S. has never ratified the court's treaty.
