I would say it is exaggeration to tell every child born as atheist as atheism in heart is impossible. The concept of GOD will exist in hearts regardless of your knowledge/surrounding/parental advice.

"A researcher at the University of Wales Trinity Saint David, calculated that around 5,200 Britons turn to Islam every year, and that the total number of converts is about 100,000. In America calculating conversion rates is even harder. The census does not ask about religion and few mosques keep registers of their members, so even the total number of American Muslims is uncertain, let alone that of converts. In 2007 the Pew Research Centre estimated that there were around 2.4m American Muslims; in 2000 President Bill Clinton made reference to a figure of 6m. Pew reckons that just under a quarter are converts."

We least bother about the enemies live outside our body.. The biggest enemy of all us lives inside us.. our own "nafs" ( evil side) and desires which makes us egoistic, impatient, dishonest, liar, namesaking moron etc.. hence for the same reason even in battles we don't forget the enemy living inside us..

However RIP.. thank you for letting us know about Russia but we least bother about enemies living outside our body.
