In another thread, I encountered a claim that I have never heard before. The claim: "The United States are a federation of sovereign, independent nation-states." I personally think this claim is beyond ludicrous.
However, because several people seem to vehemently believe in this claim, I've decided to put this argument up to a poll in order to see whether or not this is a commonly held belief that I've just become aware of in the last few days (or at least a popular argument that I've never encountered before). I accept that I could just be generally ignorant - though my history classes disagree.
Simple question: Is the United States a single nation like Germany, China, etc. OR is it a federation of nation-states similar to the EU or the UN? Why or why not?
