I have a hard time figuring out what actual practical steps you want. A dissolution of the EU and reformation of a core? Or a two speed one? And what countries would actually have a majority supporting the kind of policies you want? France - uhhh, no - a PC/LCR type candidate would get crushed by the right. That's true of Germany as well. On foreign policy, we're either talking mushy nothingness to achieve consensus, or diversity. Nor, unfortunately, do I see a potential for the kind of strong federal social policy you envision - the practical consequences would include a sharp rise in taxation in wealthier countries like France, to compensate for the relative poverty of the new states; and voters are selfish.
