I don't have a lot to contribute to this relatively serious topic and development in world politics. What I can contribute, though, is that if you want a fun perspective on the history surrounding the creation of Spain, then I recommend picking up Europa Universalis IV next time it's on Steam sale and starting a campaign as either Castile or Aragon. You can create Spain after you conquer Granada and if you enter into a royal marriage with your other half. Game isn't 100% historically accurate, but it's got enough that you may spend as much time reading wikipedia on various regions, events, people as you do playing the actual game.
