The reason the Society got away with so many failures and changes in the past was because they used a series of eclipses. They would eclipse the last problem with something bigger and bolder. They were saved from doom from the failure of 1925 by the Prohibition campaign in the United States and then the Germany campaign in 1933 and the start of the war in Europe. The next big deal was always so big, the people forgot about the last failure.
If you think about it, Witnesses have always united, prospered, and grown out of adversity and opposition. Since the 50's the Witnesses have sought legitimacy. Their last fight in the United States was the discontinuation of the military service draft. With that measure of legitimacy has come a loss of enemies and prosperity for the Witnesses. With the prosperity has come a loss of purpose.
Jehovah's Witnesses is a group born and bred of controversy and strife. Real attacks from a visible enemy and living an unacceptable public life of controversy and strife united the Witness people and gave them a sense of comradery. Now the controversy has turned into indifference and the strife has turned into prosperity. Indifference and prosperity is too boring to fire up any enthusiasm or any real growth. Prosperity is turning into their biggest challenge ever.
The "generation of 1914" change was the first real change after the start of the Internet. It's easy to see what the future holds for the group.
IMO, the apostates and the internet have taken over the role of the opposition, and it's a powerful one to them You are right, the org. thrives on the idea that the whole world is out to get them. How delusional.
