President Donald Trump said early Tuesday he had agreed with the head of NATO to meet with America's allies in Switzerland as he doubled down on his gambit to acquire the island of Greenland in a move that has roiled Europe.

"There can be no going back — On that, everyone agrees!” Trump wrote in one of several early morning statements on his Truth Social platform where he also posted a mockup photo of him planting an American flag in Greenland.

Trump disclosed he had a call with NATO Secretary General Mark Rutte and had agreed to a meeting at the World Economic Forum in Davos, where the American President plans to give a speech Wednesday.

“I had a very good telephone call with Mark Rutte, the Secretary General of NATO, concerning Greenland,” Trump wrote. "I agreed to a meeting of the various parties in Davos, Switzerland. As I expressed to everyone, very plainly, Greenland is imperative for National and World Security. There can be no going back — On that, everyone agrees!”

Trump also posted what appeared to be text messages from Rutte and French President Emanuel Macron on the subject, that latter which included an expression of befuddlement. 

"I do not understand what you are doing on Greenland," the purported text message from Macron read among praise for other Trump foreign policy moves.

Trump has relentlessly renewed a long-standing American desire to acquire Greenland, even imposing tariffs against European allies opposing his plan. The pressure has created turmoil in Europe and unease in financial markets.

Trump early Tuesday cast the acquisition of Greenland as a security imperative for the entire world.

"The United States of America is the most powerful Country anywhere on the Globe, by far. Much of the reason for this is a rebuilding of our Military during my First Term, which rebuilding continues at even more expedited pace. We are the only POWER that can ensure PEACE throughout the World — And it is done, quite simply, through STRENGTH!" he wrote.

Trump also criticized British Prime Minister Keir Starmer over plans to hand the Chagos Islands back to Mauritius.

“Shockingly, our ‘brilliant’ NATO Ally, the United Kingdom, is currently planning to give away the Island of Diego Garcia, the site of a vital U.S. Military Base, to Mauritius, and to do so FOR NO REASON WHATSOEVER,” he wrote.

The United States has secured a long-term lease for the military base as part of the transition.
