source? i don't disbelieve but that is nuclear-warhead level trivia; trust but verify :)

IDK, if there exists the stats of infant circumcision rates in Europe. May be it is possible to find some stats or something else.

As for Russia, there was never a tradition or cult of circumcision. It always accounted as Jewish and so completely inapropriate for Russian man thing. Muslim population in Russia practice circumcision, but they don't perpetrate it over infants. Jews in Russia obviously do it, but it is unsignificant amount.

This is so unusual thing for Russians that nobody even think about doing some statistics on that. May be there could be some medical reasons to do that, but definitely not on the infants. Nobody never even heard that some doctor asked parents about it on birth, muslim and jewish do that in their religious circles without any intersection with medicine.

I don't know, for Russia it is something like inserting a giant disc into lower lip practicized by some african tribes. Nobody even think about asking and especially propagandising it. It just nonexistent thing for Russians.

i wonder how many other customs could be described with There was no ____ in the places where every man could easily wash his dick ?

Obvioulsy, something connected with hygiene. F.e. Russians never had different flea-fighting devices that was not rare in some European countries, banya(sauna) was affordable for every layer of society 24/7, so there was no need for that devices.
