Part of the reason the proposed Basque referendum was so contentious was because polls showed the referendum would pass with a narrow victory. And that would sort of fuel the assertion by ETA that the Spanish state is undemocratic, no wouldn't it? And I'll give my consent to any government that does not deny a man a living wage-Billy Bragg
In the long term, I suspect that a divided Basque country, Vicaya and Guipuzcoa Basque, Alava Spanish, and Navarra a state of its own would reduce the prevalance of conflict. Significant minorities in Viscaya and Guipuzcoa support violence, but with their own state, the hardliners would lose the support of sympathizers.
This is but one example of the type of messes that nationalism let lose by Scots independence could bring. And I'll give my consent to any government that does not deny a man a living wage-Billy Bragg
