I agree that they would go into a great steep decline and lose many JW`s that have been serving them for years ,however they have millions if not billions of dollars from their sales of real estate that would tide them over for many years yet ,and they would gradually build it back up into a viable televangelistic religion that so many have done to this day and are thriving.
Dont write the JW religion off just yet ,they can re-write their history yet again.Their lawyers have been tuned in to do this for many decades ,who else do you think is running this show ,the GB are just the figureheads now ,the show ponies ,puppets ,giving the impression its a religious organization.
