Even Republicans who trust Trump’s instincts have acknowledged that the tariffs could disrupt an economy with an otherwise healthy 4.1 % unemployment rate.

“We’ll see how it all develops,” said House Speaker Mike Johnson, R-La. “It may be rocky in the beginning. But I think that this will make sense for Americans and help all Americans.”

Longtime trading partners are preparing their own countermeasures. Canada has imposed some in response to the 25% tariffs that Trump tied to the trafficking of fentanyl. The European Union, in response to the steel and aluminum tariffs, put taxes on 26 billion euros’ worth ($28 billion) of U.S. goods, including on bourbon, which prompted Trump to threaten a 200% tariff on European alcohol.

Many allies feel they have been reluctantly drawn into a confrontation by Trump, who routinely says America’s friends and foes have essentially ripped off the United States with a mix of tariffs and other trade barriers.

The flip side is that Americans also have the incomes to choose to buy designer gowns by French fashion houses and autos from German manufacturers, whereas World Bank data show the EU has lower incomes per capita than the U.S.

“Europe has not started this confrontation,” said European Commission President Ursula von der Leyen. “We do not necessarily want to retaliate but, if it is necessary, we have a strong plan to retaliate and we will use it.”

Italy’s premier, Giorgia Meloni, on Wednesday reiterated her call to avoid an EU-US trade war, saying it would harm both sides and would have “heavy” consequences for her country’s economy.

Because Trump has hyped his tariffs without providing specifics, he has provided a deeper sense of uncertainty for the world, a sign that the economic slowdown could possibly extend beyond U.S. borders to other nations that would see one person to blame.
