Excellent stuff Ultimate Axiom!
Russell's response to the incompatibility of the Bible's prophecy of "seventy years" with the historical fact implies two things. One, that the Bible is to be believed to be right whatever evidence to the contrary-- and second, that the Watchtower today have held on to Russell's principle of deliberate ignorance of available evidence. It worked for him so why change?
The madness here is seen in the Watchtower's insistence that a prophecy takes priority over evidence. Common sense tells us we cannot create facts out of stories of promises given by ancient religious visionaries.
The GB tell the flock with a smug confidence that eventually historical 'new light' will vindicate them.
The GB are away with the fairies.
