Response:

No one outside Iran wants to see Iran armed with a nuclear weapon, but this apocalyptic scenario is based on no behavioral evidence whatsoever.  The recent history of Iran makes crystal clear that national self-preservation and regional influence - not some quest for martyrdom in the service of Islam - is Iran's main foreign policy goal.  For example:

• In the 1990s, Iran chose a closer relationship with Russia over support for rebellious Chechen Muslims.
• Iran actively supported and helped to finance the U.S. invasion of Afghanistan.
• Iran has ceased its efforts to export the Islamic revolution to other Persian Gulf states, in favor of developing good relations with the governments of those states.
• During the Iran-Iraq War, Iran took the pragmatic step of developing secret ties and trading arms with Israel, even as Iran and Israel denounced each other in public.
