The EU was intended to evolve towards being a country. I don't know if that's a good idea, but an EU army is not scope creep. The central goal of the EU was to not have more wars in Europe, so it's well-aligned with the founding goal. My own opinion is that the EU should handle economic, military, and foreign policy issues. It should have centralized funding for common goods like research and environmental issues, but not to the exclusion of local funding. It should have a minimum bar for local democratic governance, but it shouldn't be very high. It should stay away from social issues, which are best handled locally. Scope of the EU is a valid area for debate. The above is my opinion. You're welcome to argue your own, but perhaps with logic, rather than as "scope creep."
