Trump hits back at Merz after German chancellor said Iran was humiliating the U.S.

Donald Trump hit back at German Chancellor Friedrich Merz on April 28 after Merz said Iran was humiliating the United States in the stalled talks over the conflict.

Reuters reported that Trump responded on Truth Social, saying Merz “doesn’t know what he’s talking about.” Reuters also said Trump mischaracterized Merz’s position on Iran’s nuclear program.

The German chancellor had said Iran’s leadership was humiliating the U.S. in the deadlocked diplomacy. But Reuters says Merz has actually argued that Iran must not be allowed to obtain a nuclear weapon.

The exchange adds another public wrinkle to an already tense transatlantic discussion over Iran. It also highlights how far apart Washington and some European leaders remain on both the language and substance of the diplomacy.

Trump’s attack is consistent with the administration’s hardline position on Iran, while Merz’s comments reflect frustration with the pace and direction of the talks.

The immediate question is whether the White House or the German government responds further, or whether the dispute remains a brief but sharp public clash.
