Armageddon, courtesy of Ahmadinejad?

This is an interesting article from Free Republic. I actually just heard about this on the radio last week and wanted to look it up.
Those of us reading this in the West might not take it seriously, but one thing that we need to keep in mind is that many Muslims take what you are about to read quite literally. The refusal of the Ahmadinejad government to reply to U.N. mandates until 8/22 fuels the speculative fire, but I wouldn't worry about any real nuclear threat. I personally haven't checked out the Iranian nuclear sites, but from what I can tell they still need a few years to develop workable nukes.
