BRUSSELS: EU leaders will rethink their ties with the US at an emergency summit on Thursday after Donald Trump’s threat of tariffs and even military action to ​acquire Greenland badly shook confidence in the transatlantic relationship, diplomats said.

Trump abruptly stepped back on Wednesday from his threat of tariffs on eight European nations, ruled out using force to take Greenland, a semi-autonomous territory of NATO ally Denmark, and suggested a deal was in sight to end the dispute.

German Chancellor Friedrich Merz, welcoming Trump’s U-turn on Greenland, urged Europeans not to be too quick to write off the transatlantic partnership.

But EU governments remain wary of another change of mind by a mercurial president who is increasingly seen as a bully that Europe will have to stand up to, and they are focused on coming up with a longer-term plan on how to deal with the ‌United States under this ‌administration and possibly its successors too.

“Trump crossed the Rubicon. He might do ‌it ⁠again. ​There is no ‌going back to what it was. And leaders will discuss it,” one EU diplomat said, adding that the bloc needed to move away from its heavy reliance on the US in many areas.
