EVEN IF ISRAEL DISAPPEARED SUNNIS & SHI'A would be killing each other as they have been doing since the 8th C! Attention Tucker, Nicky & Candy!
"Shi‘ism is distinguished from Sunnism, the other main branch of Islam, primarily by the Shi‘i belief that Muhammad’s rightful heirs as religio-political leaders, or Imams, of the Muslim community are the Prophet’s son-in-law ‘Ali and his progeny. Most Houthis are Zaydis, that is, members of a Shi‘i denomination that split off from the main body in the eighth century because of a dispute over recognition of the Fifth Imam. Zaydis do not believe, as most Shi‘a do, that the imamate must be handed down through a particular line of ‘Ali’s descendants. Today about 85 percent of Shi‘a worldwide, including the vast majority of Iranian and Iraqi Shi‘a, and the Shi‘a of Lebanon, follow what is called Twelver Shi‘ism: They believe that the Twelfth Imam was the last legitimate successor to Muhammad and ‘Ali, and that one day he will return from occultation, or hiding, to restore just rule and battle evil."
