Prediction: Iran will be in a civil war at least as intense as the Palestinian and Iraqi civil wars by the end of this year.
Physical Evidence: A significant car bombing and the inevitable failure of centralized economies, with all that implies (and that implies a lot).
I freely grant that's not a lot to go on, although it is telling that we've heard about these things. The real reason I make this prediction is cultural: The entire culture has been built on the premise that if you have a grievance, it's acceptable to bomb people. No, it's beyond acceptable.... it's your moral imperative to bomb them.
