Let's be honest on why the EU won't really work, in any sense, over the long haul.
Economically, it's impossible, for the reasons we see today... Greeks and Germans just have way different work ethics, etc...
Politically, when swift action is needed, who is going to direct it to happen? The EU either needs to get a stronger central government, or just quit before they do more harm... because you are never going to get all those nations to agree at short notice over anything controversial... and at the same time, will the larger France give up its sovereignty to allow smaller nations to interfere in their decisions, and vice versa?
