You seem to be under the impression that the Russians by large are atheists. Or that the government still promotes atheism. Let me tell you something - religion is exploding in Russia. Big time, no, huge time!!
They are incorporating it (again, just like during the times of the Tzars) in the their patriotic, empire-like attitude. "The third Rome" , have you heard that [Moscow]? The Russians see themselves as the sole protector of Orthodox Christianity. The Russian tourists that I meet in my country spend all their time visiting religious sites. They talk about it all the time. Just yesterday a Russian businessman offered to buy one of the largest old buildings in the capital of my country [it would cost a fortune] in order to make a museum of Orthodox Christianity.
Tzarist Russia was a backwater, superstitious, low-educated, peasant-bashing, stupid and callous totalitarian hellhole. But man, were they religious! Now they come back to that state again, only at a different technological level.
In the way the state uses religion to fortify patriotism and instill a sense of righteousness Russia and USA are the two sides of the same coin. This has to do with empire-thinking more than it has to do with religion IMO [although a successful argument can be made that that every religion is an empire and behaves like one]. In fact I am aghast that the religious folk happily accepts to be used in this manner by the sate. But then again, they probably like it because the state will, in turn, place special privileges for their religious institutions. Why are you, religious people, behaving like prostitutes, I often ask? Have you no shame? Some sensible people in the military of the US have complained that they were/are used as racketeers; where are the religious leaders that say "we don't want our fate to be used as political tool".
