I've long said that if Obambi wins, that we'd have to lose at least a portion of a major American city for the population to regain their senses. They'd immediately reflect on the fact that no enemy of the US was able to make another attempt during the time Bush was in charge.
And they'd probably reflect on the fact that it wouldn't have been likely under McCain-Palin, either.
I sadly think you're wildly optimistic. They would be told that it's Bush's fault and they'd believe it. I have very little faith that Boobus America will snap out of it even with an attack like that.
Just watch how they will smile and happily support the executive orders that Chairman Hussein will spew. One of them I just heard on the local news after the Sunday night game will be to reverse Bush's order on domestic oil drilling. Chairman Hussein will do that and the price of oil will climb right back up to where it was. You know it'll be the oil companies first in line for blame for obvious reasons (though when have you heard anyone say a good thing about them with gas prices being down almost $2 since their high?), and Bush and Cheney second on the basis that they lowered oil prices to help McCain and planned this after the election to sabotage Obama and drive up the price of oil to help their Saudi royal family buddies, and, of course, Halliburton.
