The book called Daniel is a historical fictional novel written in the middle of the second century BCE. Being written in the first person, it convinces the gullible that Daniel was both real and contemporary to the events described. The text takes a spin on events which had already happened hundreds of years before as imagined in Babylon but referred in part to the prevailing Persian politics. The surest way to write prophecy is after the event!
The JW organisation as 'God's only channel' has had nothing on which to claim divine attention except to predict 1914. It never did foretell WW1 but the year when paradise would arrive, so it is a dishonest boast anyway.
To expose the faulty basis for 1914 in the Watchtower would remove the only vestige of god-magic it can muster.
I get the impression that for very many years, among the upper echelons, belief in 1914 whether true or not, is a sort of in-house code for fidelity to the GB, it almost seems masonic.
