With visa-free travel, common regulations, etc., the European Union is certainly starting to approach the United States (notice the plural in "States"?) in developing a similar federal structure.

Brexit shows that there's still a major difference: member states can elect to leave. Economic penalties etc follow, and political fallout, but here in the US we fought a major war to demonstrate that states are _not_ allowed to secede from the union. (As much as many blue states might wish they could ...)

There are only two states in USA that could secede and not feel crippling economic impact. Texas and California. One Blue, one Red
