President Donald Trump’s threat to impose an additional 10 percent tariff beginning Feb. 1 on eight European allies that oppose his hopes of acquiring Greenland raises the stakes for an impending Supreme Court ruling.

President Donald Trump threatened Saturday to impose new 10% tariffs on imports from several European countries. It could unravel months of progress made during trade negotiations settled after Trump’s trade war last year.

Trump said the 10% duties on eight European countries would increase to 25% on June 1 unless a deal is reached.

“Foreign exporters absorb only about 4% of the tariff burden—the remaining 96% is passed through to U.S. buyers,” the authors of the research wrote in a study, which analyzed $4 trillion of shipments between January 2024 and November 2025.

President Donald Trump has once again drawn his go-to diplomatic weapon — tariffs — to coerce the Iranian government to end its bloody crackdown on nationwide protests.

President Donald Trump has said over the last year that money brought in from his increased tariffs would pay for at least half a dozen initiatives -- from reducing the national debt to providing dividend checks to "moderate income patriots" -- but the revenue raised so far can't deliver all of them.

Yet almost a year on, the global economy has not tanked, raising the question: Was Trump right? In my view, it’s not that tariffs are not damaging but rather, their effects are being stretched over a longer period of time. Negative consequences are currently being offset by low levels of retaliation and high levels of AI investment.

"They're not there for us on Iceland, that I can tell you," the president said in a remark that appeared to be about Greenland.
