Is there any imaginable (vaguely plausible, at least, please) political or economic situation which, if it occurred would disprove these prophecies?
Sure. There are all kinds of things, like the attack of the killer clowns from outer space, apes taking over the world and that sort of thing. But imagination and reality, while often confused, particularly by a generation raised on tv illusions, are two different things. You can imagine whatever you want, but at some point, soon, you will have to face reality. That's what I am talking about. / You Know
