>> Life in these camps is not especially good compared to asylum in Western countries

That's exactly one of my concerns here. Why doesn't for example Jordan just let them assimilate in their society, as fellow Arabs, and instead it just keeps them in camps? Of course not just Jordan, but also other more resourceful Arab/Muslim (mostly Sunni Muslim) countries such as UAE, Qatar, etc.

Wouldn't it be easier for these already traumatized refugees to integrate in Moroccan, Tunisian, Egyptian, Jordanian, Saudi Arabian, UAE-ian(?)...societies? Isn't there a "brotherhood" thing between Arabs (maybe even between Muslims? or just Sunni Muslims?)?
