TEL AVIV [MENL] -- Israel's Defense Ministry has determined that Iran could destroy the Jewish state with two atomic bombs.
Officials said the ministry and the Israel Defense Forces have conducted simulations of an Iranian nuclear attack for damage assessment and response. They said authorities have determined that two nuclear bombs that explode in the center and north of Israel would destroy most of the population and all vital infrastructure.
The assessment was issued at a conference on Iran and its nuclear program. Deputy Defense Minister Zeev Boim said two Iranian missiles tipped with a nuclear warhead could destroy Israel. Boim said even one nuclear weapon could cripple the country.
