Western intellectuals have long had a soft spot for Russia. Voltaire, the French teacher of tolerance and a great friend of Catherine the Great, said that he would gladly move to Russia, though only if its capital were Kiev, not icy St. Petersburg. Johann Gottfried von Herder, the German philosopher of enlightened nationalism, dreamed that he would obtain earthly glory as the “new Luther and Solon” for an as-yet-unspoiled Ukraine, which he would transform into a “new Greece” within the Russian empire.

And in the last century intellectuals like André Gide, Pablo Neruda and Jean-Paul Sartre all stumped for the Soviet Union as what Lenin allegedly called “useful idiots,” apologizing for its monstrosities long after the rest of the world recognized them.

To those in the Eastern Europe left — myself included — who know Russia better than most, such naïveté has long been a source of chagrin. And yet it continues, even today, as many American and Western European intellectuals do all they can to minimize the dangerous aggression by Vladimir V. Putin.

Writing in The Nation, the Russia scholar Stephen F. Cohen argued that Mr. Putin was largely blameless for the conflict in Ukraine, that he had tried to avoid it but that the West had forced his hand. In Mr. Cohen’s eyes, the West has unnecessarily humiliated Russia by inviting countries like Poland, the Czech Republic and Hungary to join NATO.
