@neologist,
The message does not change because you start with the assumption, and look for ways to claim that scripture supports it. Young men did not die in the streets. The foundations of the city were not destroyed. The walls were not laid low. Any idiot ought to know that you can't take a walled city with archers. The people in the surrounding countryside did not leave, taking their livestock with them. The land around the city was not devastated. There was no drought and the waters did not dry up. The city was not taken by force. Both when the Medes attacked Babylon and when the Persians attacked Babylon, the defenders opened the gates and surrendered. For all that that raging old hillbilly Jeremiah may have enjoyed dreaming of bloodshed and slaughter, it just didn't happen.
The message doesn't change because it's delusional, and you cling to your delusions.
