There are some prophecies which may be better than others to argue for evidence of the faithfulness of the Bible. However, we will not allow unbelievers to insist that a fulfillment of prophecy is not "universal" because they continue in unbelief
This is unjustified - the prophecy is objectively not fulfilled!
Besides, reading this thread, it is clear that the prophecies being discussed are not explicit enough to say unambigously what is being predicted. The degree of interpretation involved is high, and to me, this means it is not even possible to say what the prophecy actually is.
If there are any truly explicit prophecies, with objective confirmation from evidence outside the bible, that are not self-fulfilling, please put them forward. Otherwise they really don't prove anything.
