An Israeli Rabbi living in a Jewish settlement in the West Bank has caused a firestorm in both Israeli and Palestinian media with a new book outlining a series of Jewish theological arguments for killing those who threaten Israel or demand Israeli land...
What this could portend is the beginning of a general movement among the religious Jewish settlers in Judaea and Samaria (also known as the West Bank and East Jerusalem) to defend their settlements with violence against any Palestinian forces (or even the Israel Defense Forces, if it must come to that) who would try to shut down their settlements as part of the granting of full Palestinian state-sovereignty to the West Bank and East Jerusalem.
The ultra-Orthodox Jews in Israel are the wild card in the "peace" negotiations which is usually completely overlooked. They could turn the whole thing into chaos by getting so squeezed that they take up arms (which they are permitted to carry for self-defense against the Palestinians) in an all-out religious revolt against the secular Israeli government and its abandoning of the historically most important and the most holy parts of the land of Israel promised by God to the Jews since the time of Abraham.
Imagine a scenario where the ultra-Orthodox Jews in Israel become so enraged at Israel's complete abandonment of its heritage, its whole reason for being, that they take up arms in their tens of thousands and march together as a great army to take back the Temple Mount from Muslim control. With huge bulldozers they could knock down the Muslim Dome of the Rock (the site of the first two Jewish temples) on the Temple Mount and then the Al-Aqsa Mosque at the southern end of the Temple Mount to clear the site for the building of a third Jewish temple.
Of course, such an act would completely enrage Muslims worldwide, as the Muslim structures on the Temple Mount are the third holiest in Islam (right after those in Mecca and Medina). The Muslims worldwide could declare an all-out jihad against Israel, and a huge Iraqi Army, built up by the U.S. to defeat Iran, could, instead of attacking huge Iran, suddenly turn and attack tiny Israel instead, completely defeating it (Daniel 11:15-16), except for the walled Old City of Jerusalem (which contains the Temple Mount), which the ultra-Orthodox Jews could defend with thousands of men with machine guns lined along the tops of it walls. The Muslim Iraqi Army wouldn't want to harm the Old City in any way, seeing that it is so holy to Islam, and so the Iraqi Army could simply decide to lay siege to it until the ultra-Orthodox Jews run out of food and water and surrender.
But the ultra-Orthodox Jews could have stored up months worth of food and water, and while they are under siege they could clear the rubble from the Temple Mount and rebuild a third Jewish temple, with materials they brought with them in trucks when they first attacked the Temple Mount. They could then declare (what they could call) "the true state of Israel", which will have the Mosaic law as its law, and will practice all the animal sacrifices and temple rituals commanded therein:
"And there was given me a reed like unto a rod: and the angel stood, saying, Rise, and measure the temple of God, and the altar, and them that worship therein" (Revelation 11:1).
