“We’re going to talk about a big trade deal,” Trump said at the start of a one-on-one meeting with European Commission President Ursula von der Leyen. “We’ve been talking about it for a while, and hopefully we can get something done.”

After 70 years of being largely hand in hand in promoting democracy and capitalism around the world, the United States and Europe are now at odds over trade, climate change, taxation, privacy, Iran and defense funding. And Trump continues to try to use tariffs to pressure European leaders to meet his demands.

“Europe and America are moving slightly apart from each other,” said Rachel Kyte, dean of the Fletcher School at Tufts University and the former World Bank special envoy for climate change. “It’s not just the trade war but a fundamentally different approach to privacy and the role of business and society.”

Leaning on the same tactics he used against China, Trump threatened a 25 percent tax on European cars if Germany, France and the United Kingdom did not formally announce that Iran had broken a 2015 nuclear deal. The longtime U.S. allies ultimately did just that last week.
