One can certainly quibble with many of the details and starting assumptions, but overall given the course of play the results seem quite sound.
Yeah, towards the end when Iran closes the Straits of Hormuz and zots Saudi processing stations I couldn't see Obambi really worrying about the price of oil. I figure he might--at most--use ABM assets defensively against missile strikes against the Arabs but unless congress threatens impeachment he doesn't give a shit if Israel gets gassed into oblivion and/or the world pays $20/gallon and the economic chaos that would ensue. Jews and oil are evil to his worldview.
If Israel threatened nuclear retaliation for a bio or chem response from Iran it would be a toss-up as to whether Obama A) reluctantly enters the war to finish off Iran before they hit Israel and unleash nuclear Armageddon on themselves or B) orders US assets to intercept Israeli nuclear armed aircraft or ballistic missiles.
I also think Iran would be reluctant to drag the EU into what would already be a regional war if they even for a minute saw Obambi as pliant enough to come down against Israel. Can't say they don't have reason to think this. In fact, I would say Obambi's acceptance of the fraudulently elected and overtly repressive regime coupled with the back door treatment of Netanyahu all but guarantees Iranian intransigience because Israel is being treated as the bad guy.
