President Donald Trump’s administration appears unconcerned with the Islamic Republic of Iran’s gloating and insults about the peace plan signed this month, but is willing to make serious threats when Tehran negotiators consider breaking the agreement.

Iranian leaders seem to have zero fear that trash-talking the Americans could blow up their memorandum of understanding with the United States — routinely characterizing it as a victory for the Islamic Republic and a disgrace for the U.S. This brazen attitude could not have been any clearer than in remarks on Wednesday from Mohammad Bagher Ghalibaf, the head of the Iranian negotiating team, while speaking at a conference in Azerbaijan.
