Why was Vance's letter addressed to Mohsen Razai? David Ignatius, a senior international affairs analyst and Washington Post columnist, wrote: Washington believes that Mohsen Razai, unlike some political figures, has enough influence to win the support of the main currents of power in the Islamic Republic and advance the agreement; But his choice is associated with an important contradiction. It is estimated by American intelligence agencies that Mohsen Razai has an ongoing relationship with the leader of the Islamic Republic, and the two have spoken to each other in recent days after receiving Vance's letter. It was also said that Mohsen Razai gained more influence in this institution after the reorganization of the Supreme Council for National Security and the appointment of associates to him.
