Merge into one central state. Comeon guys you didnt see this coming when they created the Euro?? They sold there rights to national individuality along with there money.

...in Europe as tere is still regional individuality in European countries, and it will go on.
German and Spanish are not alike but they work together, as in Porugal, for exemple, Madeira people and Lisbon inhabitants are not quite alike though they share the same culture, language etc...
These differences are what make Europe as interesting, and no Europeans will tell you the contrary... Working together does not make us all alike...
