My response to this is that it shows how difficult it will be to achieve greater unification of Europe, even just within the Euro zone.
The European Union, and then the Euro zone, have been created in an attempt to create much more unification of the European countries. This has been both economic and political. However, it is a very difficult thing that they are trying to do. They are trying to get numerous separate countries with different histories and different needs to all become part of one integrated whole. This is going to be exceedingly difficult to do. Slovakia's rejection of this bailout shows how much the plans for cooperation can run up against the interests of any one nation in the zone.
