WI the Sassanid Empire was able to defeated the Rashidun Caliphate?
Would an initial Sassanid victory be able to permanently avoid conquest? Or would Persia (or at least Mesopotamia) still be conquered later? Would the Sassanid state be able to survive itself, or would it fall because of internal disputes?
And how would this affect the Byzantine-Arab wars? Would the Arabs still be equally succesful?
And what will the effect be on the development of Zoroastrianism and Islam?
