This is one of those things that is specific to the Jewish religion, in which it serves as an irreversible symbol of membership and has done for about three thousand years ... and also a subset of Americans, who do it for reasons which they suddenly find difficult to explain to their adult children.

It is very much not specific to the Jewish religion. Jews make up 0.2% of the world population while ~33% of the worlds males are circumcised. Its very much a part of the Islamic religion as well; being nearly universal in the middle east. In addition ~80% of American men are circumcised.
True but 78% of South Korean 20 year old men are circumcised, a relatively new phenomenon in the country but something that has clearly taken hold and appears to be a new normal. 90% of the Philippine's are circumcised so its not a strictly non Asian tradition.
