Gregor,
I agree on #2 tactic to keep the flock stick tight, I'm no too sure about #1. As far as I could observe until I left (only a few weeks ago), the prospect of Armageddon plays a very small part, if any, in directing JWs' individual lifes. I've not heard any JW for a long time mention in conversation that they should keep awake, in case it occurs in their lifetime, other than as an old conventional JW expression. I believe more in the power of the fear to lose social and family links, which, IMO, is in the end the last glue that keeps JWs together. No religion in that, just social pressure.
