Viv, Isa 19:23-25 spiecifies that Assyria are the agreesors working as the hand of God, also in Isa 20:3-5 shows that the King of Assyria is at some time after Sargon who is speciefied in 20;1.
Isaiah 19:23-25 is failed prophecy. Isaiah 20:1 is history. How does that add up to a specific prophecy with names, dates, events, etc.?
Isa 17 does not spiecify by whom or when, however if you apply the same standard as used to asert historical facts then it can only apply to Assyria.
That's you adding into the text, not a specific prophecy with names, dates, etc., within the text.
I am saying that as it has been argued in the discussion about Daniel a late date appears to used to dismiss it as prophetic are we applying the same rule to the rest of prophecy because if that is the case there is evidently no prophecies as we can not date the last redaction of the texts before the oldest copies we have.
Daniel is known for a fact to be an amalgamation of early and late stories. You are correct, there are no "prophecies" that can be dated to prior to the events. I was letting that slide, but since you brought it up, you are correct. There is no way to prove any of these things were written before the events happened.
