Iranian Army General Commander Ataollah Salehi spoke on LBC television (video clip here) claiming it would take only 11 days "to wipe Israel out of existence."  But don't worry, the announcer proclaims that "according to the shari'a and the law, it is forbidden to obtain a nuclear bomb." MEMRI translates

Voiceover: "Nothing can prevent Iranian missiles from targeting the heart of Israel, if Iran is subjected to a military strike by Israel. This was the response of the Iranian military commanders to the Israeli statements about a possible military strike against Iran, because of its insistence on obtaining nuclear energy. Yet an [Israeli] attack seems improbable to the Iranians, because Tel Aviv does not have the ability to go through a war with Tehran."

Iranian Chief-of-Staff General Hassan Firouzabadi: "We are fully prepared to confront any attack that would threaten the interests of Iran. We have sufficient means and the necessary force to defend our territory."

General Ataollah Salehi, general commander of the Iranian army: "The truth is that Israel does not have the courage to attack us. If we are subjected to any attack by Israel, I do not think we will need more than 11 days to wipe Israel out of existence."

Voiceover: "Tehran denies that its military preparations are aimed at attacking any neighboring country. Iran justifies its military preparedness as a means to defend Iran and the region, which may alleviate the fears and concerns of countries in the region."

General Yahya Rahim Safavi, Khamenei's chief advisor on military affairs: "Our military capabilities are not meant to threaten the neighboring countries, but only to defend Iran. Iran strives for peace, security, and stability with the countries in the region."

General Reza Pourdastan, commander of the Iranian army ground forces: "The neighboring countries can rest assured that by no means will we attack any country."

Voiceover: "But fears about Iran's missiles remain, especially among Western countries, concerned that Iran might arm its missiles with nuclear warheads, since the superpowers doubt that Iran's nuclear program is peaceful. This is categorically denied by Tehran, which says that according to the shari'a and the law, it is forbidden to obtain a nuclear bomb."
