Like “The Wizard of Oz” in reverse, a Syrian lion, once thought courageous and invincible, turns out to be less so. The house of Assad — Arabic for lion — is fast crumbling. Damascus is about to fall after Jihadist rebels captured ruling Baathist positions in Syria’s other cities. President Assad has fled the country, and his troops are defecting. Russians are retreating. Tehran’s foreign minister, Abbas Araghchi, stops calling the anti-Assadists “terrorists.”
