Island country only has oil enough to last 15-20 days, and 12-hour blackouts have become commonplace

Mexico’s president, Claudia Sheinbaum, has warned that Donald Trump’s move to slap new tariffs on countries sending oil to Cuba could trigger a humanitarian crisis on the island, which is already suffering from chronic fuel shortages and regular blackouts.

The US president signed an executive order on Thursday declaring a national emergency and laying the groundwork for such tariffs, ratcheting up the pressure to topple the communist government in Havana.

Dispiriting, deadly and unrevealing – there is a decent documentary to be made about the former model from Slovenia, but this one is unredeemable

• One adult for the 9.40am in Sittingbourne: a front row seat for Melania’s ominous UK opening
• Eggs, hats and unfettered ambition: what we learned about Melania Trump from her documentary

My audience with Melania is booked for Friday lunchtime at a retail park on the outskirts of Bristol, inside a large cinema which appears to have been swept and emptied in readiness. When Brett Ratner’s contentious, Amazon-backed documentary previewed at the White House last weekend, the guestlist included Mike Tyson, Queen Rania of Jordan and the president himself. Today it’s just me in the room and Melania on the screen. It makes for a more intimate and exclusive affair.

This mood of cosy conviviality extends all the way through the opening credits; at which point the chill descends and the novocaine kicks in, as the film’s star and executive producer proceeds to guide us – with agonising glacial slowness – through the preparations for her husband’s second presidential inauguration. She glides from the fashion fitting to the table setting, and from the “candlelit dinner” to the “starlight ball”, with a face like a fist and a voice of sheet metal. “Candlelight and black tie and my creative vision,” she says, as though listing the ingredients in a cauldron. “As first lady, children will always remain my priority,” she coos, and you can almost picture her coaxing them into her little gingerbread house.

Whether it’s Minneapolis or Greenland, the US president will do just enough to get through a damaging news cycle, then carry on as before

Don’t be fooled. When it comes to Donald Trump, what might look like a full retreat is almost always a mere tactical withdrawal, designed to buy time. He’ll step back when he’s forced to, under pressure, but will then revert the instant the pressure lets up. Too often, his opponents, whether at home or abroad, allow themselves to be played, confusing a mere pause for a surrender – and the risk is strong that they’re making that same mistake all over again.

This week, the US president won praise in some quarters for moving to “de-escalate” the war he has been waging on the people of Minneapolis. Following the killing of Alex Pretti, an intensive care nurse who posed no threat and yet was shot at least 10 times by masked agents of Customs and Border Protection or CBP, Trump signalled that he wanted to calm things down.
