Prediction again:
Israel instigates attack against Iran. US stupidly backs Israel, long war ensues. Gigantic anti-Semetic backlash in the US. Entire Middle East gangs together, Israel either scaled back drastically or does not exist.
Certainly a possibility, although my prediction (naive 15 year old that I am 
), goes something like this:
Iran launches attack against Israel, full scale warfare. US quickly joins Israel, launches massive bombing campaign against Iran, targeting mostly civilians. Iraq makes a pathetic attempt to help Iran, makes no difference. Most of the Middle East stays neutral, except for Lebanon on the Iranian side. After several years of devastating warfare for all sides, the Iranians overthrow the Government, creating a less theocratic democracy, while the US increases aid to Israel, to help it recover, and the Israeli government becomes even more hardline against neighboring countries.
ummmmmm no
First of all Iran would never attack Israel but no faults there because it was obvious you were going to say that. Also US would not attack civilans unless on massive amounts of crack-cocaine. I trust our military, would go after strictly military targets. Also Lebanon does nothing, although it could get into a civil war. I would also expect war to last for only a month or two, with possibly insurganices in Iran and Lebanon going on for quite sometime(against democratic governments). Also biggest flaw, WTF is with you thinking Iraq would side with Iran!!!
