> On top of that, everybody has been trying to murder Jews during the entire history, so there's a lot of natural selection. It doesn't seem plausible that war or murder leads to a positive force on someone's character or natural ability. There are many great tragedies where the flower of a nation's manhood has been lost in war and left the country in a worse off position to grow it's populace. The Battle of the Somme for one. Most religions and ethnic groups has at least one persecution story if not centuries of them, I don't see the evidence that it leads to a uniform positive increase in outcomes.
