The Insight books easily prove the date of jerusalems fall, simply by referencing the Kings going back from Belshazzar.
They cannot provide the names of even one missing king.
There is a lot of obfuscation around the reign of nebuchadnezzar, regnal v accession years, but they know they have successfully inculcated inability to think, ignorance and gullibility in the sheeples, so they can never crawl through the tangled web they put in those volumes. They cleverly removed passages in the Aid book that could give clues to their deception, with regard to Nineveh and the fall of Tyre.
I just got sick of their increasingly strident screaming "Listen obey or die"
