For the Europeans, calibrating next steps should start with a clear-headed evaluation of strengths and weaknesses. Despite Europe’s economic heft, its reliance on the US for everything from cloud computing to support for Ukraine gives the White House escalation dominance. China forced Trump into a partial tariffs climbdown last year by threatening restrictions on rare earths. Europe lacks a trade weapon of comparable potency and, unlike Beijing, has not spent years gaming out confrontations with the US.
