Republicans need to fall in line because Trump’s decision have paid for so far.
President Donald Trump’s latest push on Greenland is stirring debate inside the Republican Party, as some GOP lawmakers voice concern over his plan to impose new tariffs on several European allies.
The president recently announced he intends to introduce a 10% tariff on eight European nations after those countries sent troops to Greenland, a move the White House views as backing Denmark’s continued control of the strategically important territory.
Trump has argued that the Arctic region is becoming increasingly vital to U.S. national security, especially as Russia expands its military footprint. Supporters say the president is using economic pressure to protect American interests.
Tariff Plan Sparks GOP Unease
Under the plan outlined by Trump on Truth Social, the tariffs would begin February 1 and apply to Denmark, Norway, Sweden, France, Germany, the United Kingdom, the Netherlands, and Finland. If the United States does not reach an agreement over Greenland by June, the tariffs could rise to 25%.
Some Republicans, however, worry the approach risks unnecessary friction with long-standing NATO allies.
Retiring Rep. Don Bacon of Nebraska publicly questioned whether tariff authority should rest with the president, arguing that the Constitution places such power with Congress. Other GOP lawmakers have raised similar concerns, particularly about the economic impact on American businesses.
Legal and Constitutional Questions Raised
The administration is expected to rely on the International Emergency Economic Powers Act to implement the tariffs. That law is currently under review by the U.S. Supreme Court, adding legal uncertainty to the plan.
Sen. Rand Paul of Kentucky criticized the move, saying new taxes and tariffs should originate in Congress. Several Republican senators had already expressed unease about Trump’s escalating rhetoric surrounding Greenland even before the tariff announcement.
Public Opinion and Military Concerns
Trump has declined to rule out the possible use of military force to secure Greenland, a position that has further divided opinion in Washington.
Polling shows strong public opposition to that idea. A recent survey found that 86% of Americans oppose using military force to take control of Greenland. Among Republicans, roughly 70% disapprove of such action.
Some GOP critics have suggested they would consider impeachment if U.S. troops were used, though that remains a hypothetical scenario.
Republicans Still Back Purchasing Greenland
Despite opposition to military action, many Republicans support a diplomatic solution. Polling indicates that 64% of Republican voters favor purchasing Greenland from Denmark, even though Danish officials have repeatedly stated the territory is not for sale.
Democrats and independents show far less support for such a purchase.
Legislation and Strategic Importance
Pro-Trump lawmakers continue to advance legislation tied to Greenland. Rep. Randy Fine of Florida recently introduced a bill aimed at granting the president authority to annex the territory. Previously, Rep. Buddy Carter of Georgia proposed authorizing negotiations to acquire Greenland and rename it “Red White and Blueland.”
Trump allies argue that Greenland is critical to countering Russian influence in the Arctic and plays a key role in the president’s proposed Golden Dome missile defense system, which relies on Arctic-based monitoring and defense assets.
Treasury Secretary Scott Bessent recently emphasized the administration’s position, stating that America’s significant military investment in Greenland justifies stronger U.S. control.
As debate continues, Trump’s Greenland strategy has become a rare point of internal Republican disagreement — highlighting the tension between assertive America-first policies and long-standing alliances abroad.
