Ahead of Europe's largest annual security conference, NATO defense ministers gathered in Brussels today to calm nerves and stiffen spines after President Trump's threats to Greenland roiled the alliance.

Here's Nick Schiffin with more.

Today, an alliance, recently shaken by American threats, hosted a reunion to portray itself a happy family.

NATO defense ministers met in Brussels and provided words of encouragement and reassurance, including to themselves.

USA are member of NATO and they will remain member of NATO.

But to keep this in order to keep NATO to keep NATO transatlantic, it is necessary to make it more European.

Good to see you.

That Europeization of NATO, exactly the message from the Pentagon's number three, Elberts Colby.

And I think we have a really strong basis for working together in partnership, but putting NATO kind of a 3.0

NATO that's based a partnership rather than dependency.

Today, the U.S. says it provides nearly half of NATO's military posture and wants to provide

less than one-third within about five years, especially as it prioritizes its own borders, Venezuela and

the rest of Latin America, and China whose military buildup is the fastest in world history.

As Colby told the defense ministers in a closed-door briefing, we will continue to provide the U.S. extended nuclear deterrent.

But Europe should feel the preponderance of the

forces required to deter and, if necessary, defeat, conventional aggression in Europe.

It's a message the Trump administration has sent consistently, but today's delivery was with

a perhaps more constructive tone than one year ago today.

We're also here today to directly and unambiguously express that stark strategic realities

prevent the United States of America from being primarily focused on the security of Europe.

And last month.

The United States is treated very unfairly by NATO.
