Trickery is so deeply ingrained in them that they are convinced that they trick their own god with things like the chicken thing, they find ways to deceive a culture so that they can take over and squander it's resources, then run out of town like they're the victim once people realise how they have been fooled. If they were so smart, they would figure out how to live on their own without having to steal a nation's wealth. Heck, if jews were constantly being persecuted for being smart then why haven't they ever built their own city to live in, instead of taking over someone else's? Wheres Jewish Atlantis or the Jewish moon colonies? Heck is there even a single city that Jews built without stealing it from other people?
