How do I know?
Because the Ayatollah says so:
""The Iranian people openly announce that they will defend their rights [to nuclear power]... God will reprimand them if they do not do so," state radio quoted Khamenei as saying.
Naturally, he makes it clear after saying this that, of course Iran isn't going for nuclear weapons.
Yeah, I'll believe that one.
After all, God also wants Israel "wiped off the map," and we all know what God expects of his children in carrying out that divine ordinance:
Would she herself become a suicide bomber? "If God wills it," she says in a low, serious voice. "If I had the means, I would have done it yesterday."
So forgive me if I see this as being only one step away from "God wants Iran to have nuclear weapons," and an even shorter step to "God wants Iran to use the weapons to destroy the Zionists and the Great Satan (i.e. the West)."
Just add it to the list of reasons why religion is dangerous and should be relegated to the historical scrap heap of failed human ideas.
