Jeffro, my argument, and that many others, is that Biblical chronology and secular chronology correspond. Why would Babylonian scribes or the scribes after them falsify the tablets?
Sorry if I was unclear. Neo-Babylonian records agree completely with the Bible for the period in question. It is only the JW chronology that inserts 20 years into the Neo-Babylonian period. But JWs shift back all the events of Nebuchadnezzar's reign, not just the destruction of Jerusalem (and they also distort the order of events during Nebuchadnezzar's first 7 years, and place the stories in Daniel* in the wrong years).
* Daniel wasn't an actual historical figure, but the periods given in the stories are compatible with the Neo-Babylonian period.
