Is that one reason why such "character" led to frequent anti-Jew practices thru much of European history ? 

The version I heard is Jews are the lost tribe or so called God chosen ppl. Hence they are supposed to be pandai aka smart and strong and possess special character traits. This is why they are being targeted by so many others. And due to this targeting they have learnt to be resilient and to war at all cost to preserve their race continuity. Hitler almost succeeded but not enough. No one can imagine a small little area called Israel can withstand the coordinated attack from multiple countries and even win them in 2 wars. So yes Jews are special and just maybe they are the chosen ppl.
