John Derbyshire’s been asking: why is Russia our enemy?

I’ve wondered too:

A more enlightened worldview would see Russia ”” a great Christian nation, and one that has made priceless contributions to the treasure-store of Western civilization ”” as a natural ally in these perilous times. We have much in common, including ancient, existential enemies who gloat to see us fighting with with each other rather than uniting against them. Yet our stance toward Russia has been relentlessly bellicose, with our support of the Ukrainian revolution, and our actions in Syria, being only the most obvious examples.
