Born in an Algerian desert

As time goes on in this conflict between Western Sahara and Morocco individuals must wonder how long until the people of the SADR can no longer remember Western Sahara or want to return for that matter. At some point it would seem after so many decades, that those who have left and are currently refugees in Algeria must come to the realization they wont go back? or their children's children would no longer consider it home and want to come back. How many decades does it take to no longer be where your parents are from?
