whoever is elected president, whether Mahmoud Ahmadinejad or his main opponent, Mir Hossein Mousavi, will have limited impact on the issue that most concerns the outside world – Iran's drive to build nuclear weapons, which Khamene'i will presumably continue apace, as he has in prior decades. Therefore, while my heart goes out to the many Iranians who desperately want the vile Ahmadinejad out of power, my head tells me it's best that he remain in office.
