Thats sufficient.
But you still assume the "new testament" from the outset. If you did not, the "old testament" would not predict it at all.
I thoroughly disagree.
Isaiah, Danial, Psalms, Zech, Ezek et al are virtually saturated with prophecy that is
about this era
regardless of what is in or absent from the NT.
