Nuclear free zone? This is more fantasy than reality in a region of fanatical Jihadism. Nuke for peaceful purpose? This is the height of Taqiyya that is being applied to fool Israel and the world. The fact is the fanatical Islamist-Jihadist regime of Iran is hellbent on the destruction of Israel. Shortly after 9/11, Iran's former President, Hashemi Rafsanjani, told the crowd at Tehran stadium that a single nuke could destroy Israel (p.224, "World On Fire"  by Professor Amy Chua). Since then Iran's current President Ahmedinejad has repeatedly threatened to annihilate Israel in his speeches in Tehran, Kuala Lumpur and Jakarta. And the whole Islamist-Jihadist world applauded him.
