Russia is definitely more Christian than Muslim, to be sure.
Russians are unafraid to stand up to Muslims within their own Federation, and suppress them widely. Several revolutions and separatist movements within what was the old Soviet Union resulted in a number of scattered small mostly Muslim provinces, some of which the Russian Federation has had fierce confrontations.
This suppression of Muslims has not negatively affected their international relations, for the most part. They will cheerfully deal with Muslim nations, but not without extracting serious concessions FIRST.
I think we’ll see the same here under Trump’s presidency. Obama was such an anomaly. I don’t think we’ll see his like for awhile.
