Why do americans circumcise their baby boys but their european cousins don't?

Cultural: It has become an unnecessary habit in the U.S. Based on false long term health issues. Maybe the europeans have caught on.

Culture/availability: In Britain, the government health care doesn't cover circs, and rates run 10%. In France, about 30%, in the US it varies from 60-90% depending on ethnic and religious factors. I remember one British Navy officer who had his 3 boys done it the US Naval hospital while he was stationed here for studies.
