@WAB I looked over a few things and I think I know what Trump is upto with the Falkland Islands.
Look at it through the perspective of a real estate developer like Trump is at heart, I think he sees growth potential in the "market" of Argentina and by market I believe he's wanting to build up an ally in the Southern hemisphere; so he's building up the confidence in Argentina by making such statements and simultaneously ribbing the U.K. for being a hollow shell of the world naval power they once were.
Javier Milei's theatrics appeal to Trump's personality and you have to give it to president Milei he not only has the theatrics but also the intellect to go with it; he came in and cut inflated government, nearly clubbed "woke" to death like a seal and above all got Argentina to a position where it made the first payment to debt principle in the decades since their bond defaults in the early 2000's....as I understand it.
Argentina also recently(Dec 2025) took possession of six F-16 fighters of a total of 24 purchased from Denmark with assistance from the U.S.A. and I think that's a good thing having ally with super sonic jets as a part of strengthening their military power and boosting the overall self image of the nation by merely implying that Argentina is gaining stature in the world power market
So in summation, I think it's just a pat on the back to Milei while being able to get a shot in at the UK and it's naval readiness or lack thereof as well as their reluctance or inability to assist with Iran; and yes also to distract from that same conflict as we see news reals appear online of sailors from the Lincoln enjoying much deserved RNR in Bangkok.
Disclaimer - not saying it's a sound strategy, just saying I believe that's what he's up to.
