A strong Spain with a solid and well-defined foreign policy would cut off aid to Morocco and redirect it to Algeria to continue arming the Polisario Front, while giving greater visibility to the Rif movement.
But it's not going to happen. We are on the verge of seeing the pro-Moroccan social democratic party in the Spanish government replaced by a pro-Israeli liberal party, which will result, at the very least, in a neutral position in favor of Israeli interests - and therefore Moroccan interests.
The only 'achievement' that can be realized under the new government is a return to the original position on the Sahara. The rest is just false hope.
