Dear jk-ton, theirs is a false confidence and is not one iota different than the many other times they have cried "armageddon....sooooon". Every time their has been conflict their confidence has risen, only to vanish once nothing changes. The twin towers was HUGE until it wasn't. And the jws were SURE that was the beginning of the end...at the time. As other posters have said, the world wars, more recently the Six Day War, the Gulf War, the turmoil in Egypt and Syria and everywhere in the middle east...name a time when you couldn't point to the middle east conflicts and say "oh, armageddon is coming!".
Remember the story of The Boy Who Cried Wolf? The jw leaders are that boy. They repeatedly trick people into believing the same story over and over and over...the only difference being that in the story there eventually was a real wolf. But there will be no armageddon as the jws preach it.
Please don't let their hand-clapping/jw.org/somethingbigiscoming craziness overreach your solid logic. Remember that the gb and their hired consultants are masters of manipulation and have to keep things stirred up or else everyone would eventually leave. The excitement (oh, 100 years of failed prophecies, yay!!!) is manufactured to keep the worker ants busy.
You have done well to get on the road to Freedom...please stay on it!
