Looking at the cutbacks and predicting the end of Watchtower is like looking at the natural disasters happening around and predicting the end of the world.
JW's hear about earthquakes and hurricanes and start thinking that the end of the world is near. Ex-Jw's look at the yearbook stats and predict that the end of WT is near.
The greatest asset that WT has is believers. No matter what happens, no matter how many fade away, a core group of strong and true believers will always be there to prevent the org from collapsing.
