If a nuclear war between Israel and Iran were to break out 16-20 million Iranians would lose their lives - as opposed to 200,000-800,000 Israelis, according to a report recently published by the Washington-based Center for Strategic and International Studies (CSIS), which is headed by Anthony H. Cordesman, formerly an analyst for the US Department of Defense. The document, which is largely theoretical due to the lack of verified knowledge in some areas - specifically in terms of Israel's nuclear capability - paints various scenarios and attempts to predict the strategies of regional powers, as well as the US. The report assesses that a nuclear war would last approximately three weeks and ultimately end with the annihilation of Iran, due to Israel's alleged possession of weapons with a far larger yield. Israel, according to the assessment, would have a larger chance of survival. The report does not attempt to predict how many deaths would eventually be caused by possible nuclear fallout. Even if Iran gained the means and knowledge to create nuclear weapons, according to the report it would still be limited to 100 kiloton weapons, which can cause a far smaller radius of destruction than the 1 megaton bombs Israel allegedly possesses. Possible targets for an Iranian strike are the Tel Aviv metropolitan area and Haifa bay, while the list of possible targets in Iran includes the cities Teheran, Tabriz, Qazvin, Esfahan, Shiraz, Yazd, Kerman, Qom, Ahwaz and Kermanshah. The report cites Israel's Arrow missile defense system as an obstacle facing a possible Iranian strike and says that it could shoot down most of the missiles. Israel, on the other hand, would be capable of hitting most of the Iranian cities with pinpoint accuracy due to the high resolution satellite imagery systems at its disposal. Another scenario presented by the report includes Syria joining the bandwagon in case of a war and lobbing missiles with chemical and biological warheads into Israeli cities. According to the report, up to 800,000 Israelis would be killed if that were to happen. Syria, however, would be forced to grapple with the deaths of approximately 18 million of its citizens were Israel to respond with its nuclear arsenal. Israel, the report says, would launch a nuclear attack on Cairo and additional Egyptian cities, and would destroy the Aswan Dam if Egypt joined the fray.
