Inetresting to see that Ahamdinejad is now saying that the mahdi will return withe Jesus - he's some deceiver!
Well, for one, this is nothing new, and besides, it isn't just Ahmadinejad saying it. It's not even exclusive to Shiites. It's been a Muslim belief for a while now, actually. I don't know how widespread this belief is, but my understanding is that it's actually quite common. I look at this description and see a picture of the Antichrist and his false prophet. This doesn't mean that the Antichrist can't be European or even come from the Roman Catholic Church. It simply means that the Muslims will identify him as the Mahdi.
After the destruction of Isalm [possibly very soon, see Psa 83] and a possible major conflict, [WW3? like many American hawks are wanting], then there will be a call [from the Club of Rome at least] for a one world government.
Speaking as an American hawk, born and raised, I never met anyone who wanted World War Three. However, the real argument is whether or not we have a choice. If Iran gets nukes, then Iran might very well use them, even without provokation. That would be your major conflict, even if we do nothing. The only question is how to stop it, though it's probably already too late.
The east is not ready for that yet but the revived RE is a likelhood.
Is the European Union already a revival of the Roman Empire?
Well, if this character in Iran declares that anyone in particular is the Mahdi, then I'd suggest we keep an eye on the man, because if their prophecy ever gets fulfilled, even self-fulfilled, then we could be looking at the Antichrist.
