On September 3, Javier Milei used a nationally televised address to declare that the Falkland Islands are part of Argentina’s future and will ultimately have to be recovered.
He announced legislation to strengthen sanctions against companies developing the Sea Lion oil field, proposed a national security council, promised additional funding for a naval base in Tierra del Fuego, and described further exploitation of the islands’ resources as a threat to Argentine national security.
Now, an important caveat is in order: These were proposed measures, not an operational plan to retake the islands by force.
The speech was nevertheless a striking turn for a leader who was hitherto known as a bit of an Anglophile.
After all, Milei had previously cultivated relations with Britain, and described Margaret Thatcher (the Prime Minister who defeated Argentina in 1982) as a great leader.
But here is where things are getting interesting: Washington made this u-turn politically easier.
Just mere days before all of this, Trump said he was reviewing the American position on the islands.
In a subsequent GB News interview, he declined to assure Britain of US support in another conflict over the Falklands and connected the question directly to London’s limited participation in the Iran war: “Your country was not there to help me.”
Milei got the signal, sensed the political opening, and ultimately, seized on the opportunity within days.
“The US is considering this change of position because it knows that Argentina has a reliable partner,” he said, presenting Washington’s ambiguity as proof that his alignment with Trump was producing results.
But why is Trump getting involved in all this?
Why create this dangerous ambiguity and feed Milei’s delusions that he could retake Falklands?
First, we will unpack four immediate objectives that Trump may be seeking to attain via this play.
Then, and in order to understand why Trump is incentivized to play this particular card, and why he would reach for this specific lever over the UK, we need to look at all this from his perspective.
Trump sees all upside from this play and the lever may on the face of it appear to be an unusually cheap one to deploy.
But this is not so.
Incentive 1: The Defense Budget And Cooperation
The first apparent goal is to put pressure on British defense spending.
Elbridge Colby is in fact on the record (leaked emails) for suggesting that the U.S. could hit back at the UK for their failure to raise their defense spending (and not providing sufficient allied support) by punishing them over Falklands.
That was back in April.
And now, after several months, Trump subsequently confirms that the US position on Falklands was under review (although he did not formally announce a policy change yet).
Now, add to this, a former Pentagon official is now being used to make the implicit link, rather explicit.
Just look at this report from Fox:
“Morgan Murphy, a former press secretary in the War Department, told Fox News Digital that while Washington has not altered its position on Falklands sovereignty, he believes the Trump administration may apply heavy diplomatic leverage over London’s military budget.
“You don’t take the security and skip the bill. That is free-riding,” Murphy said, before adding: “Friends tell friends the check is due. Squeeze is accountability.”
People like Murphy are no longer in the current admin, so they are ideally positioned to be used as messengers where the White House wants to maintain some semblance of plausible deniability.
Now, it is important to remember that Britain is already under pressure to turn its NATO pledges into a funded schedule.
The dispute is whether London will reach 3% of GDP by 2030 on the way to the alliance’s target of 3.5% in core defense spending by 2035.
And the estimated additional cost of meeting the 2030 target is about £10 billion annually.
Murphy, while explicitly not speaking for the administration, articulated the pressure case rather bluntly: Britain should provide a dated path to 3% by 2030 and 3.5% by 2035 because “the special relationship is a privilege, not a welfare program.”
The timing increases the potential leverage too, since the new Chancellor John Healey is preparing an October Budget while Downing Street remains unwilling to make an unambiguous 2030 commitment.
So in a way, raising doubts about American support now inserts the threat over the Falklands directly into that budget debate.
