At least that's the inside information.
Interestingly, Trump apparently thought about asking Denmark if it wanted Puerto Rico, which is close to Cuba, in exchange for Greenland in his first Presidency, or as we should more accurately state, his Presidency. He was talked out of that, as that's a stupid idea.
Something talked him out of Greenland, and I don't think it was the stock market. Somebody pretty clearly told him to wrap that up or else. We just don't know what the else was. It was probably that he'd be removed, however.
Cuba is probably thought to be a better bet, except that you can't really effect regime change by kidnapping a country's leader, and changing the government in Cuba would take a full scale invasion. It's a big island and the Cuban military will fight back. That's what kept the Kennedy Administration from trying that. Yes, we could win, but at the cost of U.S. lives.
Of course, economic pressure will be applied first.
Cuba is an easy target as it has no real friends who can aid it. Trump's a bully and its easier for him to kick sand in the face of Cuba than it turned out be for Denmark, who has a lot of friends, including a lot of friends in the U.S. And Marco Rubio is likely fixated on it.
Funny thing is, we could achieve the same by just lifting our long running embargo on the country and let its population get a taste of what a non communist economy can provide.
And what will be the causa belli? It's not drug running. It doesn't have oil.
Democracy? Well, we haven't installed that in Venezuela.
