In the Europe of the last century, many Jews were poor or simple workers, not academics, lawyers, politicians, etc. That made them really smart and savvy and able to read tea leaves.
I think in the first half of the 20th century, that is certainly true. I think the prosperity of the second half of the twentieth century changed things, for sure.
I think it’s a difficult thing for non-Jewish Americans to understand how many (perhaps most?) Jews worldwide are utterly indifferent to Israel. Then there’s a small number that are actually hostile.
