Good luck to Catalonia today in breaking free from the suffocating grip of Spain. I hope that the Francoists in power in Madrid do nothing to provoke violence.
There may be an important precedent here on how to proceed in the event of the central government refusing to grant a referendum. I was pleased that Alex Salmond came out last week and said that a referendum is not necessarily the only route for Scotland. While that position is undoubtedly correct in international law, I had suffered pooh-poohing from Leadership Loyalists in Scotland every time I mentioned it. Hopefully now Salmond has spoken, the sheep will stop bleating. We do not know how things will pan out with Westminster and we must not close off our own options.
There is one interesting side issue in Catalonia. The astroturf anti-independence organisation Ciutadans (Ciudadanos in the rest of Spain) is a classic creation of Western security services. Its purpose is to counter both Catalan Independence and still more, Podemos, and maintain a secure right wing Spain in NATO. But unusually it is not the CIA that has been in the lead, but the BND, the German overseas security service. This is an outlier for a newly assertive policy by the BND, so the results will be watched particularly closely in the more obscured corridors of Berlin.
