Quote from Martinghoul:
Well, the first thing to mention would be that, apparently, it's illegal for a country to unilaterally exit the EMU. This is a view that's was formulated by the ECB legal counsel, Phoebus Athanassiou, in this working paper (I think I have posted a link in another thread a while ago):

I dont believe that is meaningful. If Greece leaves the EMU what is Germany going to do, send tanks to Athens? The whole legal framework has been trashed, they are doing whatever they want these days
