In these troubled, twisted times of mankind, I sumize that there are fewer and fewer things that Almighty God looks upon and says: "This is good."
But, He can't help but be entertained with the volume of "dooms day" prophets.
One can only imagine His shaking His head and smiling at the pathetic attempts to "know" His detailed plans for us.
I agree. Many 'prophets' and speculators have come and gone. IMO, the problem though with this guy is that he's not just speculating, but would like nothing more than to control the timing and while he may not achieve the 'biblical' armageddon, I don't think it will keep him from trying. From what I've read, if he is successful he believes it will force the return of the Hidden Imam, an event that Ahmadinejad has decided should happen now.
