“The supremacy of America in the Western Hemisphere will remain unchallenged,” declared Trump recently, sparking a flurry of international reactions.

Over the last two days, Trump has made several statements that have caught the attention of global leaders, particularly regarding Greenland. On Sunday, Trump reiterated his stance, emphasizing the strategic importance of the sizable North Atlantic island for the United States’ national security.

“We need Greenland… It’s incredibly strategic right now. Russian and Chinese vessels are prevalent across Greenland’s waters,” Trump remarked to reporters while aboard Air Force One.

He further stated, “From a national security perspective, acquiring Greenland is essential, and Denmark may not be equipped to handle the situation.”

“We need Greenland from the standpoint of national security, and Denmark is not going to be able to do it.”

Responding to Trump’s latest comments, Greenland Prime Minister Jens Frederik Nielsen said in a statement: “The current and repeated rhetoric coming from the United States is entirely unacceptable.

“When the president of the United States speaks of ‘needing Greenland’ and links us to Venezuela and military intervention, it is not only wrong. It is disrespectful.

“Our country is not an object in great-power rhetoric. We are a people. A country. A democracy.

He later said in a press conference that Greenland was “not in the situation where we are thinking that a takeover of the country might happen overnight”.

“You cannot compare Greenland to Venezuela. We are a democratic country,” he said.

Trump has repeatedly stated that he wants to annex Greenland, a huge, resource-rich island of 2.16 million square kilometres, claiming that the autonomous Danish territory is needed for US national security, although he has also cited “economic security”.

Both Greenland and Denmark, a NATO ally of the US, are staunchly opposed to the idea.

Trump had harsh words for Colombian President Gustavo Petro on Sunday, describing him as “a sick man who likes making cocaine and selling it to the United States, and he’s not going to be doing it very long”.

When pressed by a reporter on whether those comments meant there could be an “operation” in Colombia in the future, Trump said it “sounds good to me”.

Petro defended his government’s track record on combating drug trafficking in a nearly 700-word post on X, touting what he described as “the largest cocaine seizure in the world’s history”.

He added: “I am not illegitimate, nor am I a narco. I only have as assets my family home that I still pay for with my salary.”

Petro said he had ordered targeted bombings against drug-linked armed groups while adhering to humanitarian law.

However, cocaine production in Colombia has reached record highs, according to the the United Nations Office on Drugs and Crime.

Petro, a former member of the M19 guerrilla group, later said he would himself fight to defend Colombia.

“I swore not to touch a weapon again … but for the homeland I will take up arms again.”

Petro angered the Trump administration, which cancelled his US visa in September, after he called on US soldiers to disobey orders.

Trump on Sunday said military intervention was unnecessary in Cuba, a key ally of Venezuela, because it was “ready to fall”.

“I don’t think we need any action,” Trump said. “It looks like it’s going down.”

“I don’t know if they’re going to hold out, but Cuba now has no income.

“They got all their income from Venezuela, from the Venezuelan oil.”

But US Secretary of State Marco Rubio called the Cuban government “a huge problem”.

“I think they’re in a lot of trouble, yes,” Rubio told NBC’s Meet the Press.

“I’m not going to talk to you about what our future steps are going to be and our policies are going to be right now, in this regard, but I don’t think it’s any mystery that we are not big fans of the Cuban regime.”

“If I lived in Havana and I worked in the government, I’d be concerned.”

At a rally on Saturday in front of the US Embassy in Havana, Cuban President Miguel Díaz-Canel promised not to let the Cuba-Venezuela alliance go down without a fight.

“For Venezuela, of course for Cuba, we are willing to give even our own life, but at a heavy cost,” Díaz-Canel proclaimed.

Trump has frequently accused Mexico of not doing enough to clamp down on drug cartels.

On Sunday, he said drugs were “pouring” through Mexico and that “we’re going to have to do something”.

Trump added that the cartels in Mexico were “very strong” and warned that “Mexico has to get their act together”.

In a phone interview with Fox News, Trump said he had asked Mexican President Claudia Sheinbaum if she wanted the US military’s help in rooting out drug cartels.

Sheinbaum has repeatedly rejected the US intervention in Venezuela and the seizure of Maduro.

“Mexico reaffirms a principle that is neither new nor open to ambiguity,” she said on Monday in a news conference.

“We categorically reject intervention in the internal affairs of other countries.”

Responding to Trump’s accusations that Mexico had not done enough to combat drug-trafficking cartels, Sheinbaum asserted: “Mexico co-operates with the United States, including for humanitarian reasons, to prevent fentanyl and other drugs from reaching its population, especially young people”.

“We do not want fentanyl or any drug to get near any young person — whether in the United States, in Mexico, or anywhere else in the world.”

Again rejecting the notion of US military action on Mexican soil, Sheinbaum said she did not think the United States was seriously considering an invasion of Mexico.

Trump also repeated his warnings to Iran, where anti-government protests have entered their second week.

“If they start killing people like they have in the past, I think they’re going to get hit very hard by the United States,” Trump told reporters Sunday.

Last week, Trump said that if Iran “kills peaceful protesters, which is their custom, the United States of America will come to their rescue. We are locked and loaded and ready to go.”

One Iranian human rights group estimated that 16 people had been killed in the protests so far.

CNN cannot verify that tally.

At the end of last month, Trump warned Iran against any attempt to rebuild its nuclear and ballistic missile programs.

After meeting with Israeli Prime Minister Benjamin Netanyahu, Trump said he had heard Iran was “behaving badly. … I hear that Iran is trying to build up again, and if they are, we’re going to have to knock them down.”

Iran’s supreme leader, Ayatollah Ali Khamenei, said the ‌Islamic Republic “will not yield to the enemy” and that rioters should be “put in their place”.

The US bombed several of Iran’s key nuclear facilities in June, amid Israel’s 12-day war against the country.

The attack ended what had been a stuttering process of bilateral US-Iranian talks designed to rein in Tehran’s nuclear program.
