Not really. America stands for something, they wrote a whole document about it.

There is a big difference between being "American" and being something like "German" because Germany has existed for so long as different governments and the thing that ties it together is not an ethos, but an ethnicity. Being American is different, there's no ethnicity that makes one American, there is only it's ethos. The ideals written in the declaration of independence are American values.

And that's the weak link of tying ideals and values to a location like a country:

The group elected to lead and represent this location also represent ideals and values, so THEIR ideals and values become inseparable of the location they were elected to represent.

For a certain period in the mid-1900s, "German values" meant something different than it did before and after, because Germany was represented by a different leader...
