"This Tariff will be due and payable until such a time as a Deal is reached for the Complete and Total purchase of Greenland," Trump wrote from his home at Mar-a-Lago in West Palm Beach, Florida.
The announcement seemed to deliver on a threat the president made Friday to impose tariffs on countries "if they don't go along with" his designs on Greenland. It also ignored the sentiment of the thousands of people who marched in Denmark and Greenland's capitals wearing red hats with the slogan, "Make America Go Away."
"You cannot buy Greenland, you cannot buy a people. It is so wrong, disrespectful to think that you can purchase a country and a people."
“We are demonstrating against American statements and ambitions to annex Greenland,” Camilla Siezing, chairwoman of the Inuit Association, said in a statement. “We demand respect for the Danish Realm and for Greenland’s right to self-determination.”
Julie Rademacher, chair of Uagut—an association of Greenlanders who live in Denmark that helped organize the demonstrations—said at the Copenhagen protest, as Deutsche Welle reported: "We are also sending a message to the world that you all must wake up... Greenland and the Greenlanders have involuntarily become the front in the fight for democracy and human rights."
One Greenlander who attended the Copenhagen protest was Naja Mathilde Rosing.
"America has a sense of feeling they can steal land from the Native Americans, steal land from the Indigenous Hawaiian people, steal land from the Indigenous Inuit from Alaska," she told NPR. "You cannot buy Greenland, you cannot buy a people. It is so wrong, disrespectful to think that you can purchase a country and a people."
Protests were also held in the Danish cities of Aarhus, Aalborg and Odense.
Greenland is a semiautonomous territory of Denmark with a population of nearly 57,000, 85% of whom do not want to join the United States.
Greenland's Prime Minister prime minister Jens-Frederik Nielsen joined a crowd of 5,000 in the island's capital city of Nuuk, where people carried signs reading, "Greenland is already great," and "Yankee, Go Home!"
“We have seen what (Trump) does in Venezuela and Iran," one protester, named Patricia, told CNN. "He doesn’t respect anything. He just takes what he thinks is his… He misuses his power.”
Yet Trump did not acknowledge the feelings of Greenlanders in his post on Saturday. Instead, he was focused on the actions of eight European countries that have sent small numbers of troops to the island, accusing them of "playing this very dangerous game."
The leaders of the eight countries and the European Union pushed back against Trump's threats.
French President Emmanuel Macron likened Trump's designs on Greenland to Russian President Vladimir Putin's invasion of Ukraine.
"No intimidation or threat will influence us—neither in Ukraine, nor in Greenland, nor anywhere else in the world when we are confronted with such situations," he wrote on social media. "Tariff threats are unacceptable and have no place in this context. Europeans will respond in a united and coordinated manner should they be confirmed. We will ensure that European sovereignty is upheld. It is in this spirit that I will engage with our European partners."
Swedish Prime Minister Ulf Kristersson posted: "We will not let ourselves be blackmailed. Only Denmark and Greenland decide on issues concerning Denmark and Greenland."
European Commission President Ursula von der Leyen wrote: "Tariffs would undermine transatlantic relations and risk a dangerous downward spiral. Europe will remain united, coordinated, and committed to upholding its sovereignty."
Denmark's Foreign Minister Lars Løkke Rasmussen, meanwhile, said Trump's tariff announcement came "as a surprise," noting that it followed a meeting with Vice President JD Vance and Secretary of State Marco Rubio earlier in the week, which he described as "constructive."
Trump's latest tariff threat also drew criticism from US lawmakers.
"To threaten Denmark—and now six other NATO allies—in a crusade to take Greenland threatens to blow up the NATO alliance that has kept Americans safe and destroy our standing in the world as a trustworthy ally," wrote Sen. Chris Coons (D-Del.), who led a bipartisan congressional delegation to Denmark that coincided with Saturday's protests.
Rep. Don Beyer (D-Va.) said: "Trump has no legal authority to tariff American allies to bully them into backing his brainless attempt to seize Greenland. This is against the law, it’s a total disaster for America, and Republicans in Congress and the Supreme Court need to find their spines and stop it."
" Donald Trump wants to be Tariff King, but he's nothing more than a tax troll with no legal authority to levy these tariffs, no support from the American people, and no support from his allies."
Sens. Bernie Sanders (I-Vt.) and Patty Murray (D-Wash.) also called on Congress to act.
"Trump is raising tariffs on eight NATO allies because they rightly support Denmark's sovereignty in Greenland. Destroying our closest alliances to take Greenland—which Denmark lets us use freely already—is insane. Congress must say NO," Sanders wrote on social media.
Murray posted: "To my Republican colleagues: ENOUGH. It's time for the Senate to vote to block these tariffs and to block the use of military force against Greenland. Trump is tearing apart our alliances in real time and the economic and diplomatic consequences will be catastrophic."
Sen. Mark Kelly (D-Ariz.) also appealed to Republican colleagues, and pointed out that it would ultimately be Americans who would pay higher prices as a result of the tariffs.
"Troops from European countries are arriving in Greenland to defend the territory from us," he wrote on social media. "Let that sink in. And now Trump is setting tariffs on our allies, making you pay more to try to get territory we don’t need. The damage this President is doing to our reputation and our relationships is growing, making us less safe. If something doesn’t change we will be on our own with adversaries and enemies in every direction. Republicans in Congress need to stand up to Trump."
Sen. Ed Markey (D-Mass.) posted a video from the streets of Boston, evoking the spirit of the American Revolution.
"Donald Trump wants to be Tariff King, but he's nothing more than a tax troll with no legal authority to levy these tariffs, no support from the American people, and no support from his allies. Enough is enough," he said.
Ultimately, Trump's ability to play "tariff king" will be determined by the Supreme Court, which could rule as soon as next week on the legality of many of his tariffs.
