I was just pointing out that the UNHCR view could be expanded given the time to when refugees could return,. Children could figure. Depends how long the period is. Not supporting the idea but wondering what the actual legal framework is.Also, please note that Palestinians are the only group of refugees in the world (there are about 117 million refugees worldwide) where refugee status is hereditary.
I also wonder how many would return or if some should be allowed to because of where they are. That would depend on how they are treated. It varies even in terms of where from west bank or gaza strip. They are really limited in Lebanon for instance. Jordan depends on where from. Egypt rather weird as it seems some can still go there but money needed going on one interview, Odd bits around a bit here
