I always feel the JW's have to walk a fine line... they desperately want some of their prophesies to come true, but of course once they have judged a particular prophesy 'to have occurred', they have now used it up (if you know what I mean). Potentially they then run the risk of having to back down and admit what they thought occurred was wrong too. I suppose that is a good reason to pluck out somewhat dubious prophesies and fear monger with them!
I know exactly what you mean. Sad thing is that they've done just that, and with no mass fall out. This is part of the reason many of us are here today. Think Christ's enthronement and presence, 1914, who really are the faithful and discreet slave, new light, and many more. These are all instances where they used up one prophesy only to have an "Oh, shit!" moment, and then they changed it with new light to suit their purposes. With their power, they were able to present the history of the doctrine in a favorable light due to indoctrination so that nobody noticed (or those who did weren't affected enough to realize the true impact of the change). The more time that passes between these types of things, the easier it is to play it off. But now with the internet, this is becoming more difficult to hide.
