Since the Supreme Leader of Iran, Khamenei, is 81 maybe Joe Biden is looking for a shuffleboard partner. I can’t think of a better reason. Since Trump had Qasem Soleimani, Major General of Revolutionary Guard, killed back in January; it is doubtful that Iran is going to want a new deal with America. Oh yeah, and now there is the assignation of the head nuclear guy Mohsen Fakhrizadeh.
