I don't remember the hype leading up to 1975, but I do remember the big hype in the early to mid 1980's, when "The Generation" hit 70 years and the UN declared an International Year of Peace. Convention talks were along similar lines as "we are the end of the end of the last of the last days." I was pioneering then and I remember distinctly being so relieved I was because that meant I would make it through. Let's see...that was more than 25 years ago now!!
More recently, the 2009 convention talks repeated the word "imminent" to describe Armaggedon's timing, in literally--I mean literally--every talk on the program. I kept particular notice. Let's see...that was three years ago.
Imminent? I think not.
