...that wants to act like a country. With a unified political and economic policy.

No, it doesn't. The EU is not intended to, and has never been aimed at, being a country. It's not that type of federation or institution. Sure, the folks who see Bilderbergers behind every couch are convinced that the European project is intended to bring about a single-country One World Government (or whatever). But that's not what it is and not what it's for.

Then there's nothing else to do except think outside the box and find other means to speed the war along towards a conclusion that kicks Putin out of Russia.

No one disagrees. By all means, let's find things that will actually speed the war to getting Putin out of Ukraine. I think everyone on this board would entertain a proposed solution that could actually work. Rather than things that can't be done. The EU doesn't have the power to impose sanctions that will block Russian oil imports without Hungary's assent, and Hungary isn't agreeing. It does no good to blame them for not doing something they don't have the power to do.
