Because of Israel's small size, it will be very difficult to sustain a nuclear attack. Given that Iran has now developed nuclear weapons, Israel has no choice but to expand its borders in self-defense. We must take over neighboring Arab countries and populate them with Jews from different parts of Israel and from the diaspora, maintaining settlements and Israeli military presence, gradually empowering (and arming) these groups of Jews to become self-sufficient in defense and ability to wipe out amalek so that IDF presence can eventually leave. Of course no Arabs we conquer will have any voting rights or say in Israel's leadership. There must be an emergency aliyah plan where Jews from all over the world will be resettled in various places of current middle eastern countries, upon conquest by Israel. Either we attack Iran now, or this is the only logical step for self-defense that we will need to take in the next 5 years or so.
