bradleeM: The reason why that Britain and America circumcise is because there is a very strong belief that these two countries are descendants of the Hebrews and are bound by the covenant that God made with Abraham and his offspring. All of Abraham's descendants circumcise their male offspring.

There are those that find medical reasons for circumcising that do not feel comfortable with the religious reason. But that is really the reason behind those two countries circumcising. Also the British Royal family believes they are the direct descendants of the Royal line of Israel begun by David, each of their monarchs are crowned on the seat of David and over the Rock from Jerusalem that both David and Solomon were crowned.

I know this is more than you wanted to know, but there are historical reasons for a lot of things going on today that people are not aware or do not remember.
