I say "GO PuTIN!!"
True Cristianity has no problem with such circumstances. Only 'institutionalized religion' has an issue.
Jesus said "..where TWO or more are gathered in my name, there I am also". This simple arrangement has nothing to fear. It is sacred and protected by the Holy Spirit.
True Cristianity has even prospered within the totalitarian Watchtower institution and despite its leadership's best efforts to weed it out. So it will have no issue in Russia.
But watchtower is screwed.
