There is no talk of firewalls, or of simply letting Spain go, or of the European banking system being re-capitalised to compensate for the losses that it would suffer. Nope. This is it. The cancer has now spread to the vital organs of the EU. Spain is not a peripheral Mediterranean country. It is not an insignificant player in the political project. It is not a marginal going-along-for-the-ride-and-the-free-money passenger on the euro train. Not only is its economy so large as to be indispensable, but its ties with Italy mean that the Italian economy (which is the third largest in the EU) would be fatally compromised by its fall. “Itexit” is almost unpronounceable, so perhaps it’s fortunate that it will never be required: after Spexit, there would be nothing left to exit from.
