Okay. So let's say that Saudi Arabia, Iraq, and Jordan join Egypt and Syria in the war against Israel. Officially and with real force, I mean, not just de facto. Let's handwave away Israel's tactical, technological, and organizational superiority for a moment -handwave-. The Israeli army cracks under the pressure and Israel itself is invaded. As the state crumbles, the Israeli government launches several tactical nuclear weapons into its enemy's lands in a desperate final bid for victory, or failing that, survival, or failing -that-, revenge. Cairo, Alexandria, Damascus, Baghdad, Amman, Riyadh, and most heinously, Mecca, are all vaporized in an instant of terror. Vengeful Arabian troops tear Israel apart, and massacre hundreds of thousands of Jews. To boot, they're now in possession of what few nukes Israel had left. The Israeli government, shunned from almost every nation for their actions, ends up in South Africa.
