We’ve long had your back, now it’s our turn. That is how the famously transactional U.S. President Donald Trump is framing his demands that allies help him with the Iran war. He wants to call in IOUs for decades of U.S. security guarantees. The string of refusals indicates that his stock of European goodwill is low. Trump has put allies through the wringer since his return to the White House, bullying them over tariffs, Greenland and other issues, and now demanding — not just requesting — assistance with the Iran war. This time, they’re punching back.
