I cannot see how Israel could be so stupid even thinking about attacking the (some) 1000 Iranian sites related to their nuclear enterprise - for a start Israel simply does not have the resources. If they were so stupid, the outcome would be unthinkable and one which the USA certainly could not afford to happen.
As relatiliation, Iran would attack tanker traffic in the Straits of Hormuz with silkworm missiles (supplied by their ally, China), thus stopping the shipment of oil from Saudi Araabia, Kuwait, Iraq and UAE. Oil would not just go over US$ 140/barrel, it would probably rocket to at least $500/barrel !!!!! Pprune would go out of business due to there being no aircraft to fly in the World, therefore no pilots, Trolly Dollies, Engineers and the like - no fuel.
Shiite and Sunnies would join forces and kick the US out of Iraq and the rest of the Middle East - the USA has never and could never win a guerrilla war and certainly not one occurring in several theatres at the same time.
Syria, Hezbolla in Lebanon and in Gazza would join in against Israel. It is also highly likely that the Saudi Government would be deposed and their military would join in the "free for all".
Investment in the USA would suddenly dry up sending the US Dollar into a spiral until it reached parity with the Zimbabwe Dollar thus causing major problems at home.
Iran would continue to export its oil to China by tanker until they were attacked by the US from their base in Diego Garci - that would bring China into the conflict with its million stong military machine and nucear weapons.
Simply what one would call World War 3 !!!!!
No need to go through any flight training - we would all have wings!
Is that what you really want???
