Good points, joe and sir.
I think the way they have it set up, some new member of the governing body would have to be that person. It would have to be some benign seeming leader type who had secret ambitions.
They are really ripe for it.
But also, the way they now manipulate people, maybe we wouldn't see a 75% drop off. There wasn't the same mentality back then. It wasn't really 'you must follow only us, or you DIE and Jehovah will HATE you' as it is now.
