I like the itty bitty teeny tiny quote from the 2011 WT... which says (basically) 'if you go by the business tablets from Babylon's very own time period (instead of the huge picture of a rock (from 200 years later, from a different country) with a crack thru it, featured, highlighted, debated and discussed in detail as if it were the messiah of all discoveries) then Babylons fall was in 587. Period.
All of the blabbering they do in those two articles (cleverly broken up into two different months so you can't remember the "we'll discuss this later" crap they always do to divert your attention) is only done to make themselves look like they have done soooo much research.
