You can't just look at what is happening with Jehovah's Witnesses. The world is not stable. Terrorism is not dead. The rivalry between the Eurasian Heartland (Russia+Former Soviet Republics) and the USA/NATO is very close to a serious conflict. Putn has the beginning of a rebellion which will make him extremely dangerous as he looks for things to distract people. Pakistan is going crazy and they have nukes. The overthrow of governments in the Middle east have brought in a new crop of radical fundamentalists. H1N1 is just a mutation away from being really deadly.
People will be looking for some basis to keep going. JW's are organized, disciplined, and trained to draw people into their fold and drench the newcomers in love. Don't under estimate the power of organization. When things get chaotic people will hold onto anything. Think of cancer victims who grab onto worthless cures because they offer hope.
Look at how far JW's got on World War I coinciding with the JW's prediction of somthing big happening in 1914. We know that the 1914 date is bogus but that coincidence has been fuel for everything JW's have said and done.
For example. Insurance companies have built in the risk of a nuclear device being used on a large american city and the foremost target is NY.
What if a nuclear bomb goes off in NYC AFTER JW's have sold their property and moved a 100 miles away? That's all the JW's would need to keep them going another 100 years.
The really important forces that shape the future are the ones no one can predict. Who would have thought that the Charles Russell, described during divorce proceedings as an amorous jellyfish would have spawned an organization with close to 8 million members. Who would have thought that a science fiction writer (Hubbard) would inspire a religion with the power of scientology.
The present as well as the past do not predict the future. The only thing you can say is that the future is likely to be "crazy".
