Dissolving Spain

Also a foreigner may become angry on behalf of Spain.
Regional nationalist parties and politicians are attacking the foundations of the Spanish state, to the point of demanding the right of leaving Spain if that pleases them. The Basque government proposed this in their "Ibarretxe-plan" and the Catalan government is at the moment preparing a "statute" for their region where they proclaim themselves as a nation, demand to be able to collect all taxes and decide their distribution, and have their own national sports teams....
I cannot see any other reason for this policy from the regional nationalists, than hunger for political power.
