Why would Spain had to take importance Europe? Portugal historically was concentrated in the sea. Spain should be able to do that. The King Philip II of Spain had to chooise of move the capital to Lisboa (to concentrated in the sea), move the capital to Barcelona (to concentraded in the mediterranean) or have the capital in Madrid. The only reason that Spain had to interview in Europe was to help their Habsburg cousins or defend the Mediterranean and Italy of Ottomans/France or to fight protestantism. A Spanish ruler should have the optioon to say f*** Europe, lets go to Americas.
