If the Covenant were to bombard Arda, Sauron and the Ringwraiths would still survive. With most of the Free People of Middle Earth dead, he would easily be able to regain the ring. He would also probably be allowed to join the Covenant as the orcs aren't humans and corrupt it to his purposes over time.
