I think it is a wonderful thing that Russia is teaching Christianity in the schools.

This doesn't mean that the Russians automatically become friends of Uncle Sam. The Russian empire was emphatically Orthodox when it tried to make a grab for the West Coast in the 19th century, but then decided it couldn't reach (i.e. defend such an acquisition). Russia being Orthodox did not prevent it - prior to imposing Communism as the state religion in 1917 - from almost going toe-to-toe with the British empire on several occasions.

The British Empire's being officially Christian did not prevent it from going toe-to-toe with Russia and actually helping the Ottoman Empire AGAINST fellow Christians. (See the Crimean War and the threat of war in 1878). At least Russia was defending the Christians there, while Great Britain and especially Germany were betraying them.
