Non-violence is trendy in Western Saharan resistance. In the spirit of keeping things both effective and pacifist, Sahrawis and their allies should check out this extensive e-book about non-violent resistance. Produced by the Centre for Applied Nonviolent Action and Strategies, the book discusses tactics used across the world, using protests against Slobodan Milosevic in Serbia as a model. If their ideas helped stopped Milosevic, I'm sure they can be employed effectively in El Aiun.
Weirdly, I wasn't able to find it in any other languages. If translations aren't available yet, I'm sure they will be soon--for Western Saharan purposes I'd like to see one in Spanish and Arabic.
