According to the Filthful and Disgraceful Slavebugger, it could come within the next 3-6 months. They are not currently expecting to get out of 2008 (but they said that in 2006 and 2007, too).
How reliable are they? They predicted the end for 1914, and it didn't come. They tried again in 1915, 1918, 1925, 1941, and 1975. Many on this board remember 1975. Later, they pushed in the mid 1980s (I remember hearing that we would not make 2000 sometime in the 1980s). And here we are, well past 2000.
Unfortunately, they might be much closer to starting the Second Dark Ages than to predicting successfully Armageddon. All it takes is for a few Value Destroyer Training School grads to fix the witless congregations using the methods that got them in the mess they are in (and they are likely to not accept anything less than 100% success after the 2006 False Religion Disaster and this past REJECT Jesus Party invitation campaign that did not get finished), and then they will have the whole nation captive. Then they will rejoin the UN, this time as a member nation, and make it official. Information control on a worldwide basis and ownership of everything and everyone will then be a forgone conclusion.
Hopefully, we will be successful in ruining the Watchtower Society before they get the chance to do that. If we successfully ruin the Watchtower Society, Armageddon as we know it might never come.
