US President Donald Trump has offered his bluntest explanation yet of how he views power on the world stage: the only real limit on what he can do, he says, is his own sense of morality.

In an interview at the White House, Trump dismissed the idea that international law or global institutions meaningfully constrain his authority as commander in chief. “My own morality. My own mind. It’s the only thing that can stop me,” he said, when asked what limits exist on his ability to use military force, economic pressure or political coercion abroad.

Pressed on whether the United States is bound by international law, he replied that it “depends what your definition of international law is,” making clear that, in his view, he alone decides when such rules apply.

The remarks amount to a stark articulation of a worldview in which national strength, not treaties or post-war norms, determines outcomes, the New York Times reported.

Power, unpredictability and coercion

Trump also made clear that he believes his reputation for unpredictability and his willingness to use force are tools of diplomacy. During the interview, he took a call from Colombia’s president, Gustavo Petro, who has publicly expressed fear that the US might target his country after Trump’s recent military action in Venezuela.

The call, conducted off the record, was a textbook example of what officials privately describe as coercive diplomacy. It came just hours after the administration announced it was withdrawing from dozens of international organisations aimed at multilateral cooperation.

Trump appeared emboldened by recent events. He cited the strike on Iran’s nuclear programme, the rapid removal of Venezuela’s leadership and his renewed push to take control of Greenland as proof that decisive action gets results.

Greenland and the logic of ownership

Greenland, in particular, reveals how Trump thinks about power. Although the US already has wide military access under a 1951 treaty with Denmark, Trump insists that is not enough.

“Ownership is very important,” he said, describing the vast Arctic territory in the language of a property developer. In his view, possession offers psychological and strategic advantages that no lease or treaty can match.

When asked whether securing Greenland or preserving NATO mattered more, he acknowledged it might ultimately be a choice.

A selective view of precedent

Trump rejected suggestions that the Venezuela operation sets a dangerous example that China could use against Taiwan or Russia against Ukraine. He argued that Venezuela was a “real threat” in a way Taiwan is not, even while acknowledging that Beijing sees the island very differently.

He insisted that China’s leader, Xi Jinping, would not move against Taiwan while he is in office. “He may do it after we have a different president,” Trump said, “but I don’t think he’s going to do it with me.”

Few constraints, at home or abroad

At home, Trump suggested courts can block him only “under certain circumstances” and hinted he could repackage policies, such as tariffs, if judges strike them down. He also reiterated his willingness to deploy the military domestically under the Insurrection Act if he believes it is necessary.

US Congress, meanwhile, has begun debating a resolution to curb his war powers in Venezuela, after Trump suggested US involvement there could last for years.

The interview leaves little doubt about the president’s governing philosophy. In Trump’s world, sovereignty, alliances and international rules matter less than raw power and personal judgment. And in that system, the ultimate check is not law or institutions, but the man in the Oval Office himself.
