Everyone should watch 'Sons of the clouds, the last colony' if they can manage it.
Its a doc about the people of the western sahara and how they continue to be unlawfully evicted from their land despite pathetic token UN efforts to resolve it because its in the interests of the Yanks and the French to keep it that way.

Its on netflix currently.

cheers for the heads up andyh, Mark Thomas the british comedian talks about these guys.
