New York Times: “Three Iranian officials, who spoke on the condition of anonymity to describe sensitive diplomacy, as did other diplomats who discussed the matter, said Iran had stopped engaging even in indirect talks through mediators with the Trump administration.”“While Iran left open the possibility that Pakistan could serve as a conduit if talks resumed, the response suggests that Mr. Trump’s dramatic threat, which one U.S. official said was intended to force Iranian concessions, may have backfired.”
