German politicians seem to have lost patience with Athens. Blustering about throwing good money after bad, they have shown a new eagerness to throw Greece out of the currency union, at least rhetorically. They are not alone. Similar sentiments have surfaced in Austria, Finland, the Netherlands and even Estonia. Understandable as such talk is, an expulsion of Greece is not as easy as these naysayers seem to believe and would almost surely cost the eurozone more than further accommodation, a lot more. On the assumption that politics will follow at least vague cost-benefit calculations, the likelihood then is that Europe, for all the tough talk, will find a way to keep Greece in the currency union.
