Hello KJ,t there are more references from isaiah's and jeremiah's future babylon that would exist in the end times with the bood of revelation's babylon. Anyone that actually reads it will have no doubt that a real tangible land is being described.
I agree that if you consider Isaiah, Jeremiah as well as Revelation and others, that a clear picture of what 'end time' babylon will look like... and it is certainly a land (or nation). It would be interesting I think to post here a list of the attributes of babylon that we find in the prophets, and then look for a land that matches those attributes (if any) rather than taking a preconcieved idea and looking for scripture that supports it....
Here is one attribute: it is a debtor nation
'...Woe to him who stores up what is not his: how long can it last! he loads himself down with debts. ' (Hab 2:6)
