If the lebanon War is any indication of Israel's current war-fighting capabilities, this extremely unlikely lovely little war with Iran will probably result in a whole lot of civilian deaths and destroyed infrastructure unrelated to things nuclear - unless the Iranians are processing uranium in diary plants. Also, if Israel were to attempt such a foolish thing, it would immediately incur the wrath of every nation on earth, including the United States, since this option is now OFF the table -no matter what Bush says for domestic consumption. Further, without the approval of the US, Israel would either have to violate the sovereign air space of several countries or take the long southern route over the Red Sea and attack from the Indian Ocean - NOT VERY LIKELY. And, even if it chooses this circuitous route, it would then have to contend with the Iranians' formidable air defenses. Finally, there is no obligation that a "Think Tank" report has to make sense.
