The hope started to die in the '90s. In 1991 a JW friend of mine for 13 years, I was his best friend, was engaged, and we sat in his driveway and talked about the difficulties of being married with the tribulation and persecution being so near.
How often does anyone talk about that now?
When the Cold War raged, and the UN strong-armed ideas, and there were all kinds of problems, the Watchtower and Awake had something to chew on. 9/11 was bad, Katrina was bad, but they turned into positives. The human spirit wins out. Gods on the other hand remain quiet.
