"would need pesmission...."
...need permission from Khamnei who is now under pressure from both the pro-Ahamdi-Nejad IRGC and Ayatollah Mesbah Yazdi, who is vying to replace Khamnei, dying of cancer.
Hard for permission to be refused under the circumstances.
Ahmadi-Nejad does not have the international brains but he has the "fire-power" support of those he has placed in office and who are mostly ready to support Hojatieh leader Mesbah Yazdi. And/or Ahmadi-Nejad of the Hojatieh persuasion himself.
Sadly the nutcase A-N, has all the clout he needs or wants.
Incidentally "an" in Farsi means "sh*t" or "t*rd" so the prez's initials are most appropriate.
