You're right, the USA is huge and highly diverse as well. Yet, I'd still say it's more of a unit than the EU is, in many ways, and especially more so than "Europe". That's what I meant with "Europe is not a unit like the USA is"; not that the USA has absolute unity and Europe has none. But I may be wrong about the USA's cohesion on a deeper level, I've never been there and only see it through an outsider's lens.
