All Spain can do is criticize? The Arab league seems to have felt "concern" rather quickly. Are any Western countries, particularly European, expressing "concern"?
I don't see where Spain has any validity. These were the same guys who after all turned tail and ran out of Former Spanish Morocco and Spanish Sahara. No better than the Brittish who have decided to betray the Gibraltars to the Spaniards by agreeing to share the sovereignty over Gibraltar. The same people who betrayed Hong Kong to mainland China.
Go figure, the Brits fought a war to keep the Malvinas (falklands) and a few sheep but fold like a cheap camera elsewhere like Hong Kong.
I wonder when Morocco will claim the Canary Islands. I bet the Spaniards won't give those up without a fight.
