But, more alarmingly for Madrid, that argument is no longer coming exclusively from Rabat. Questions over Spain’s centuries-old control of the fortress cities have also been raised in a U.S. Congress report, and by Israel’s ambassador to the U.N. “Ceuta and Melilla are not to be touched,” Defense Minister Margarita Robles said during a press conference on Monday. “Everyone must be very clear that Spanish territorial integrity and sovereignty are not up for debate.” The government’s rejection of Morocco’s claims has done little to reduce worries in Spain over what would happen if Rabat dials up the pressure.
