I see this as the wonderful art of predicting events after they have happened.
Throughout history, we have read and learnt about nations fighting nations, earthquakes, false prophets and lots and lots about Israel. It is much like the writings of Nostradamus. In its vaguest sense it is all-encompassing and with very little imagination can be applied to any event in any time past or present. And because it is all-encompassing, the future as well. Very clever way of writing, mind.
Mystic Meg always used to predict lottery winners whose name began with a J. Now considering the number of people named Joe, John, James, Jane etc, it is highly unlikely with that sweeping generalisation that she could ever be wrong. She never said a name and she never said how much. Damnit! the woman couldn�t even tell us the numbers.
