It's Tuesday, January 20th.

I'm Caitlin McKay for The Wall Street Journal, and here's the AM edition of What's News, the top headlines and business stories moving your world today.

President Trump has fired off a series of true social posts reiterating his plans for Greenland and telling reporters that the U.S.

is the only country that can ensure peace.

The post followed days of escalating tensions over the territory and with the subject set to take center stage as world leaders gather in Davos, Switzerland.

There, the president has agreed to meet with Mark Rutte, the secretary general of NATO, and other parties to discuss Greenland.

Trump also shared a screenshot of what appeared to be a text message with French President Emmanuel Macron, which read, quote, It comes after a French government spokesperson yesterday said the U.S.

was crossing a new threshold of coercion.

That punctuated a day of hectic diplomacy, with Danish and Greenlandic officials meeting with Ruta and the U.K.

government.

Here's Danish Foreign Minister Lars-Luka Rasmussen.

This is a fast-developing story.

Bring us up to speed on where we are this morning.

Marcus, you've got a great story out along with the journal's David Luno about the collapse of trust between European leaders and the U.S.

and how that's now forcing Europe to reassess its reliance on Washington.
