Well, from an Australian perspective, I'm not exactly a fan of the US. Plenty of folks over here detest America for its military aggression, double-standards on human rights, embarassingly poor education standards, and tendency to produce tourists whose loud mouths are only matched by the sheer amount of idiocy coming out of them.
Having said that, some of those criticisms can also be applied to Australia, what with our near-genocide and continuing impoverishment of Aboriginal Australians and all. But we're not so silly as to lower our tax base to unsustainable levels while complaining about paying too much tax, and we at least have a good idea about the world outside our borders (e.g. we'd never be so silly as to make a post on a global forum that assumes the readership are entirely from the US).
Personally, I actually hope that the US manages to hold together longer than expected (our most conservative, pro-US, foreign policy experts, are expecting that the US will be eclipsed by China around the year 2050 - the less conservative commentators are expecting that to occur much sooner). The reason is that however awful the US is, they're likely to be better than China - not that I have any animosity towards China (culturally, and on a social level when travelling, I've always found the Chinese exceedingly pleasant people to spend time with), but their foreign policy is unmitigated, shameless imperialistic power-grabbing (as opposed to the US's mitigated, half-embarassed and hence comparatively restrained power-grabbing). Also, as a democracy, the US has one more check on military aggression that China won't have to face (though its expansion thus far has been entirely economic rather than military, and their government seems sensible enough to avoid another full-blown cold war).
