You're arguing against the statement "The US is a single sovereign nation" States having sovereignty is a distracting non-sequitur. It's not relevant. The original comparison was States to EU members. If you want to argue they all have 'sovereignty', fine. They all have a thing called 'sovereignty'. But Italy doesn't care about Oregon's sovereignty. Italy doesn't deal with Oregon as a nation. Oregon can't declare war on Italy nor negotiate peace. Italy doesn't recognize Oregon's governor as a Head of State. For all intents and purposes, to Italy and the EU, Oregon is an administrative district not a "sovereignty". A Greek citizen cannot move to Sweden and vote in national elections as easily as a Texan can move to Massachusetts and vote in state elections. There are a lot of reasons for that which have zero to do with State "sovereignty".
