"Despite suicide bombings and numerous wars, it has not resorted to use these weapons." As if Israel might have considered use of such weapons as an antidote for 'suicide bombing'!? Iran are no more likely to use a nuclear weapon than Israel.(Did Israel ready these weapons for use in 1973?). Your idea that Iran might 'lend' out a nuclear device or two to 'proxies' is not credible either. It is not as if Israel would not know where such weapons originated from in such a scenario. It would be as if Iran had launched a nuclear attack from its own soil. The response would be the same. Hence Iran would be as likely to 'lease' these weapons as Israel would be to use hers, no more or less. The talk about 'Messianic' urges is not that credible either. The home of Messianism is rather Jerusalem than Tehran, and in Jerusalem as well as the settlements, Messianism is flourishing.
