It isn't that Netanyahu did as much as Bush to destroy the illusion of the American Super Power. Iraq, the nation which we declared 'Mission Accomplished' a month after we charged in, and are now being thrown out of next year did much of that. There is also Afghanistan to which we have committed more troops than the Soviet union and which has defeated use for even longer than it defeated the Soviets has done much. What Netanyahu proved is that the American Super Power can't even bring a dependent nation of insignificant size to heel. Obama might be cowardly enough to commit the USA to Iran, but if he does it will finish off the USA as a world power just as certainly as the Armada finished Spain.
