“Selling the F-35, or American systems for that matter, will certainly become more complicated for American companies,” said Gesine Weber, a Paris-based fellow at transatlantic think tank German Marshall Fund.

“An important factor in the purchase of the F-35 by European governments was the idea that European defense would be built on a transatlantic basis in terms of strategy, institutions and capabilities,” she said, adding that “the Trump administration is in the process of dissolving the transatlantic link, and the purchase of American systems will therefore no longer have any added value for Europeans.”

“If you keep punching your allies in the face, eventually they’re going to stop wanting to buy weapons from you,” said a Western European defense official, granted anonymity to discuss the matter candidly. “Right now we have limited options outside of U.S. platforms, but in the long run? That could change in the coming decades if this combativeness keeps up.”
