What happens if a country tries to pull out of the Euro? I mean is there even a precedent for it? If someone (say Luxemborg) does pull out do German soldiers go marching in to make them change it back?
I don’t know really. There was a buzz a few years back about Germany doing so itself. It won’t result in a war, but it might result in harsh economic sanctions that could cripple whichever country left.
Here’s an article on the subjecty: http://www.iht.com/articles/ap/2009/02/12/business/Europe-Euro-Woes-Glance.php

There is no provision for a country pulling out of the Maastricht Treaty. That is what increasingly worries outsiders - the Euro-zone has not planned for a crisis such as this. There is no provision for a country leaving in an orderly manner, or for tossing out a non-compliant country in an orderly manner.
This is one of the problems with the Euro: there is no “plan B.”
