German Chancellor Friedrich Merz said the U.S. is being “humiliated” by Iranian leaders as President Trump struggles to negotiate an end to the war, Bloomberg reports.In unusually candid terms, the German leader said he didn’t see “what strategic exit the Americans are now choosing,” adding that Tehran’s negotiators are proceeding “very skilfully — or indeed very skilfully not negotiating.”The result is that an “entire nation is being humiliated by the Iranian leadership, particularly by these so-called Revolutionary Guards.”
