What I don't understand is the idea that the EU as a superpower is less plausible than Russia?
I don't think the US would be a superpower if the treaties, tariffs, and military control were parceled out to the individual states and each state governor and state assembly decided when to work as a block and when to act independently.
When asked, Americans are Americans first, then whatever state they come from second.
Europeans are whatever state they come from first, European second.
Most European countries haven’t seen per capita GDP growth since the beginning of the millennium.
They’d rather preserve their “culture” than compete and survive, and it’s starting to show up in the data.
I'm not convinced that much has changed since, and you definitely can't be a super power without an army.
