Whatever the Watchtower goes through in the near to mid-term future will not re-capture its heyday. It will splutter, see here-and-there growth (especially in 3rd world countries where even a motor mechanic can successfully start up a religion)
They may see some spurts of growth just after some unfortunate world events, like massive earthquakes or another large terrorist attack, even if the novel H1N1 flu gets really bad....but very short durations as the world goes back to status quo.
The hardest thing for me to accomplish with my wife is to show her that the world we are living in is not a bad place, in fact we are in a pretty good time to be alive.........unfortunately, that is not what the WTBTS is printing, so it must not be true....because you can never trust statistics....sigh.
