That would make us look much like many of the former colonies of European countries, or like the US colony of Cuba before its revolution.
Financially, we seem to be becoming a colony of our creditors, who will no doubt be snapping up American companies once the Dow goes below 10,000. (Or maybe they'll wait a bit longer). Real estate is already being sold; the Chrysler Building just was acquired by out friends in Dubai. But even if the country falls completely apart at the seams financially and constitutionally, or even becomes a fascist dictatorship, there are still all those pesky nukes. So there would have to be a satrapy; the leadership of the U.S. would be taking orders from America's creditors while still probably continuing the charade of free elections.
Sometimes I think that Bush and the Neocons are all a bunch of Communists in drag who are intent on destroying the country.
