A review of this shows Iran is no military match for Israel alone or with the support of others. So, where is the threat?

Even if they had a nuclear weapon (which they don't), surely using one would result in, as Ahmadinejad recently said, hundreds of Nuclear weapons used against Iran in retaliation (inside military sources have reporter Israel has quite a few of it's own, and the with the support of others the use of more).


Iran's options to an Israeli attack

Israel attack capability


""Doesn't Israel have a nuclear bomb?

Israel, is not a party to the NPT (Nuclear Non-Proliferation Treaty), so is not obliged to report to it. Neither are India or Pakistan, both of which have developed nuclear weapons. North Korea has left the treaty and has announced that it has acquired a nuclear weapons capacity.

On 18 September 2009, the IAEA (International Atomic Energy Agency) called on Israel to join the NPT and open its nuclear facilities to inspection. The resolution said that the IAEA "expresses concern about the Israeli nuclear capabilities, and calls upon Israel to accede to the NPT and place all its nuclear facilities under comprehensive IAEA safeguards... "

Israel refuses to join the NPT or allow inspections. It is reckoned to have up to 400 warheads but refuses to confirm or deny this.""
