President Trump has declared that the United States will implement 10% tariffs on several European nations if Denmark does not consent to the “complete and total purchase of Greenland,” cautioning that both global security and U.S. national defense are in jeopardy.

The announcement was made in a detailed Truth Social post on Saturday, where Trump contended that the U.S. has effectively subsidized Denmark and other EU countries for many years by not imposing tariffs and by offering what he called “maximum protection.”

“We have subsidized Denmark, and all of the Countries of the European Union, and others, for many years by not charging them Tariffs, or any other forms of remuneration,” Trump stated.

“Now, after Centuries, it is time for Denmark to give back — World Peace is at stake!”

Trump wrote that both China and Russia are interested in Greenland and claimed there is “not a thing that Denmark can do about it.”

“They currently have two dogsleds as protection, one added recently. Only the United States of America, under PRESIDENT DONALD J. TRUMP, can play in this game, and very successfully, at that!” Trump wrote.

“Nobody will touch this sacred piece of Land, especially since the National Security of the United States, and the World at large, is at stake.”

Trump asserted that Denmark, Norway, Sweden, France, Germany, the United Kingdom, the Netherlands, and Finland have traveled to Greenland for “purposes unknown,” creating a highly dangerous scenario for the planet’s safety and survival.

“All of the above-mentioned Countries… will be charged a 10% Tariff on any and all goods sent to the United States of America,” Trump wrote.

He said the tariff rate will rise to 25% on June 1, 2026.

“This Tariff will be due and payable until such time as a Deal is reached for the Complete and Total purchase of Greenland.”

In recent weeks, Trump has focused on Greenland, the world’s largest island located at a strategic Arctic crossroads, and first suggested the potential for tariffs on Friday.

As a semi-autonomous Danish territory, Greenland hosts a key U.S. military base and its strategic significance is increasing as melting ice reveals new shipping routes and access to abundant natural resources.

In his Saturday post, Trump said the U.S. has attempted to buy Greenland for over 150 years, but Denmark has consistently declined.

He linked the acquisition effort to modern weapon systems and the “Golden Dome,” noting that hundreds of billions are being spent on associated security programs that can only achieve peak performance with Greenland under U.S. control.

“The United States of America is immediately open to negotiation with Denmark and/or any of these countries that have put so much at risk, despite all that we have done for them, including maximum protection, over so many decades,” Trump wrote. “Thank you for your attention to this matter!”

These comments from Trump emerge as his administration is waiting for a Supreme Court decision regarding the legality of certain tariffs he enacted in 2025.
