What would an Islamist invasion of Israel look like?A new video disseminated by an Iranian extremist organization depicts masses of jihadist operatives from organizations including Hamas and Hezbollah just as they are about to march on Jerusalem.The chilling propaganda clip calls on Muslims to unite for the "inevitable" destruction of Israel, which is to be "erased from the annals of history."The video shows soldiers and operatives from the Iranian Revolutionary Guards, the Iranian-backed Shia Badr Organization, Hezbollah, and the Hamas movement's Kassam Brigades."The youth will definitely see that day when it comes," the graphic reads.Earlier this month, Ayatollah Ali Khamenei released a new book titled Palestine, which outlines his case for why Israel must be wiped out and how. "The solution is a one-state formula," he writes.He said this "practical and logical mechanism" would have Israel under Muslim rule with some Jews being allowed to stay as a "protected minority" but only after proving "genuine roots." He advocates strict apartheid against Jews saying that they would not be allowed to vote in a future Muslim state while Arabs would have full rights.He claims that his plan would promote "the hegemony of Iran" while removing "the West's hegemony" from the Middle East.
