THE GUARDIAN WEEKLY: The latest issue features ‘Showdown’ – Minneapolis, Ice and A Moment of Truth.

Is the worm turning against Trump? Last week saw a concerted pushback against the US president by western allies over Greenland. This week, it is on the domestic front where the Trump administration seems to be buckling – this time under intense criticism after the killing of another American citizen by federal agents in Minneapolis.

The massive winter storm that swept across North America last weekend could not obscure from the nation video footage of an ICE agent shooting dead Alex Pretti, an intensive care nurse and father of three who was seemingly rushing to protect a woman as she was pepper-sprayed by Border Patrol personnel.

As our Washington bureau chief David Smith writes in this week’s big story, the events were seen by many as clear evidence of fascistic overreach and a potential moment of reckoning for Trump in the US. A wave of condemnation from politicians across the political spectrum led to a swift softening of tone from the White House, though not before leading administration figures had wrongly tried to pin the blame on the victim.

From Minneapolis, Rachel Leingang reports on the sense of shock and fury in the city, while in a stark commentary, Francine Prose voices her fears that the US may be on the brink of an authoritarian takeover.

THE GUARDIAN WEEKLY: The latest issue features ‘On Thin Ice’ – Why Trump wants Greenland – and what it means for the western alliance.

The dystopian nightmare of 2026 continued apace this week with Donald Trump seemingly hell-bent on taking over Greenland, either by purchase or military force if necessary, while potentially collapsing the entire western security alliance in the process.

Updates were delivered by the US president to European leaders in a trademark stream of social media insults and invective. As ever with Trump, it’s hard to tell if it all should be read as maximalist positioning ahead of a negotiation, or a genuine precursor to a military attack. But as Patrick Wintour and Jennifer Rankin write in this week’s Big Story, the damage among fellow Nato members already looks to have been done.

Melting sea ice has much to do with Greenland’s increasing strategic desirability. With the help of some great graphics, visuals editor Ashley Kirk explains what’s changing in the Arctic and who lays claim to what.
