4: Cueta is even less Moroccan. Again ruled by Rome, Vandals, Visigoth and Byzantine. Even when it was ruled by the Moors Cueta and much of Spain were a part of the same country. When Fez did become an independent country, it competed with Grenada (Spain) for Cueta. 

Cueta and Melilla are like the Channel Islands. When France and England were one nation and those island are now England even though its next to France. Parts of Morocco and Spain were a united country. 

5: Catalan history; I see this written often and it has its own history. Very misleading. For the last 500+ years that history has been part of a United Spain. 
It's a shared history. 

If Catalan wants independence, it should be done within the law like how  Scotland negotiated with Britain. It didn't occur over night but decades of negotiations.
