President Mahmoud Ahmadinejad has been reported as saying in official meetings that the end of history is only two or three years away. He reportedly told an associate that on the podium of the General Assembly last September, he felt a halo around him and for "those 27 or 28 minutes, the leaders of the world did not blink … as if a hand was holding them there and it opened their eyes to receive" his message.
