Quite sad IMO. I don't know where they get the will to live under such conditions.
They get it from being professional 'refugees' and supporting a lunatic culture for their entire lives. Those 'poor souls' might have become perfectly content Jordinians or even Americans had they not been allowed to feed their delusions on the world's welfare and the UN's not particularly subtle anti-semitism.
What's past is everyone's fault, not just those terrorist/refugees;
what's needed to end it is likely to be tough cookies for grannie.
