Mr. Putin is no archvillain in this understanding of America-Russian relations. Rather, he personifies many of the qualities and attitudes that conservatives have desired in a president of their own: a respect for traditional Christian values, a swelling nationalist pride and an aggressive posture toward foreign adversaries.

In this view, the Russian president is a brilliant tactician, a slayer of murderous Islamic extremists — and not incidentally, a leader who outmaneuvered and emasculated President Barack Obama on the world stage. And because of that, almost any other transgression seems forgivable.

“There are conservatives here who maybe read into Russia things they wish were true in the United States,” said Angela Stent, director of the Center for Eurasian, Russian and East European Studies at Georgetown University. “And they imagine Russia and Putin as the kind of strong, traditional conservative leader whom they wish they had in the United States.” To these conservatives, she added, “Russia is the true defender of Christian values. We are decadent.”
