In an opinion piece for a U.S. newspaper, Iran's UN envoy argued that "the U.S.' approach toward Iran has no clarity or cohesiveness. Instead, the policy is driven by an obsessional antagonism". "The U.S.' proposal of dialogue with Iran faces three major hurdles", the ambassador assessed: "talks cannot be productive if they are couple with intimidation, coercion and sanctions... the Trump administration does not speak with a united voice on the need for a dialogue with Iran... any future deal [reached with the U.S.] might face the same fate [as the JCPOA], with no guarantee to the contrary". "The U.S. policy of maximum pressure against Iran has failed", he went on to argue. "Pressure will not work".
