Israel does not need the US to defeat Iran. Just read Isa.10, Psalm 83 or Ezekiel 38. ISRAEL WINS!
Prophesies will get you, no matter what you do. But wars must be planned and executed as if lives depend on them, because they do. If the end result is the fulfillment of a prophesy, so be it. But prophesies are not scripts. They’ll get you no matter what you do.
