U.S. President Donald Trump hosted German Chancellor Friedrich Merz at the White House on March 3 for talks that traversed highly sensitive issues, including U.S.-Israeli strikes on Iran, Trump’s new threats of tariffs, and Merz’s recent trip to China.
Merz arrived in Washington from Berlin as Germany and France announced plans to deepen cooperation on nuclear deterrence - a move framed by European leaders as an adaptation to shifts in the transatlantic relationship amid persistent threats from Russia and concerns about instability tied to the Iran conflict.
Fresh from a meeting with Chinese President Xi Jinping, Merz sought to preserve the constructive relationship he has built with Trump over the past year, aided in part by Germany’s leadership in increasing defense spending. Still, the discussions required delicate diplomacy because of European unease over the legal basis for the Iran strikes under international law and widespread apprehension about the U.S. threat to impose additional tariffs on global goods.
Merz was the first European leader to travel to Washington after two developments that have complicated transatlantic ties: the U.S.-Israeli attacks on Iran - which, according to officials, killed Iran’s Supreme Leader Ayatollah Ali Khamenei and other Iranian leaders over the weekend and have disrupted one of the world’s key oil shipping lanes and thrown global air transport into chaos - and the U.S. Supreme Court’s February 20 ruling that Trump’s emergency tariffs are illegal.
Although the visit had initially been expected to focus on trade, aides and analysts said the U.S.-Israeli strikes were likely to dominate. That operation has prompted questions in Europe about whether it met the required legal justifications on the international stage and about the next steps the United States and its allies might take.
On Sunday, Merz declined to condemn the U.S. airstrikes outright but stopped short of full endorsement. He said, "We recognize the dilemma," and elaborated that repeated attempts over past decades had not deterred Iran from seeking nuclear capabilities or from oppressing its own people. "So we’re not going to be lecturing our partners on their military strikes against Iran," he said.
Observers in Washington suggested the Trump administration did not expect major announcements from the meeting. Jeff Rathke, president of the American-German Institute, a Washington-based think tank, said the administration did not anticipate significant outcomes from the talks and predicted that "it makes it inevitable that the U.S. and Israeli attacks in Iran will be more of a focal point." Rathke added that this line of questioning could present a diplomatic challenge for Merz, noting, "He might be asked directly whether Germany supports the U.S. and whether Germany would provide material support to the U.S. campaign, if asked."
Beyond the immediate fallout from the strikes, the summit also allowed both leaders to address strategic and economic competition with China. Charles Lichfield, director of economic analysis at the Atlantic Council’s GeoEconomics Center, said Trump would likely press Merz on his recent trip to China to gather insights ahead of his own planned visit in less than a month. Lichfield suggested Merz could report back "about what he heard and what he saw in China, and say, ’We need to do something together. We’ll be stronger against China together,’" adding that industrial overcapacity and global imbalances were central elements of the U.S. agenda for the Group of 20 this year.
The visit also offered Merz an opportunity to press for greater clarity from the United States on its next steps in Iran. Julianne Smith, who served as U.S. ambassador to NATO under the previous administration, said Merz could use the trip as "a fact-finding mission to try to determine, ’Do you guys have a plan for the day after?’"
Context and implications
- Diplomatically, Merz entered a fraught environment in which European partners are weighing legal and strategic questions about recent military action while also managing economic concerns tied to trade and potential new tariffs.
- Security cooperation in Europe is evolving: Germany and France’s announcement on deepening nuclear deterrence cooperation signals a shared response to perceived changes in the transatlantic security landscape.
- On trade and economic policy, the combination of the Supreme Court ruling on emergency tariffs and Trump’s ongoing threats to deploy tariffs creates uncertainty for global commerce.
The White House meeting underscored how rapidly shifting geopolitical events - military confrontation in the Middle East and the economic policy disputes between Washington and trading partners - can intersect and shape high-level diplomacy. For both leaders, the meeting served to assess immediate fallout from the strikes, consider coordination on China, and test the limits of transatlantic cooperation in a period of heightened uncertainty.
