I don't disagree with your historical recitation Rolex. With the exception that I do believe Iran is harboring A-Q, either turning a blind eye to them or giving them some support. People I know back from Afghanistan have told me that they're quite certain A-Q use Iran as a safe refuge, just as A-Q do in the Pakistan border areas.
However, I do think Ahmadinejad is an idiot for provoking Israel.
Without the "wipe them off the map" comment, I think this situation would progress as NK, Pakistan, India, Israel and China did. Fact is, nobody wants to screw with a nation that has nukes. Undeniable, proven by recent history; and the "world community" (UN) can do jack-all to stop a nation bent on having nuke weapons. The UNSC isn't going to authorize any invasion of any country to stop them from joining the nuke club.
Without the "wipe them out" comment, this would go to the UN, angst and anger would be expressed and Iran would join the nuke club and the world would go on.
I think Ahmadinejad put his foot in it. I'm not sure the Israelis will let them become a nuclear power after that. An attack by Israel would be handled the same way. Shock, outrage and horror by the bystanders and the world would go on.
Because.... whose gonna screw with Israel? They have nukes.
It's quite a club for the members and I'm not suprised so many would like to join.
