Don't think it matters what the spanish constitution says. Not when you have millions on the street on a region with 7.5 million people. But I don't know if they will be allowed to remain in the eu. The region is pro europe and doing well economically. So the eu may want to keep them in somehow. But that would be an exception. And could cause other regions to get more support for doing the same. And spain will probably try to prevent it. Look at their position on kosovo for example.
So a part of a nation wants something really bad, the laws get disregarded? I'm pretty sure that it is not as simple as that. Even though the odds are that Catalonia might separate itself from Spain, this will probably be a very complex process and will carry a lot of problems with it. I've only been in Catalonia when it comes to Spain (last year) and they were rallying for the separation even then. It looks like the people really want this to happen.
Why is someone part of a nation? Did they sign a contract to be such? Were they born within the nation? Remember, somebody else is telling them that this is a nation. Are they within because they were tempted by some benefit that the nation offered them? If they own private property, is it in the nation simply because someone else said so?
Perhaps the government has slaves, and the people don't know it. Consider this for any nation, any government, any people. The boundaries and borders are disappearing. It shows by the way people are interacting internationally.
The U.N. is there to capitalize on this whole thing when the governments fall apart.
this movement needs to be stamped out.
How do you stamp out over 1 million people? Keep in mind that Catalonia is the second region in Spain (by population) and has ~15.9% of the total population (total ~46 million). Catalonia is also first by
GRP (nominal).
That's what happens in the States every election. Usually the presidential elections are close elections. Thus 51% get what they want, and 49% are forced into it. Then the 51% realize the mistake they made, and there is a bitter taste in their mouth. What most of them don't realize is, that by their voting they are participating in the system, and agreeing to whatever is done to them.
