Could Obama be the 12th Mahdi that Iran was referring to?
Sure would seem that way.
Doubt it. For one thing he is black or at least half black (Kenyan i.e. African) & traditionally Iranian Mullahs have looked down on blacks. Best he could be to them is Gholam (servant of) "Mahdi". More plausible.. So, 0 could be known as "Gholam Hussein".
