“They push buttons,” says Timothy Snyder, a professor of history at Yale. “What button of ours are they pushing here? What are they trying to get us to do?” Vladimir Putin is posturing toward a costly invasion of Ukraine, on the false pretext of protecting Russian-language speakers in the country. Why? In a wide-ranging conversation, Snyder talks with David Remnick about how to understand Russia’s aggression, the idea advanced by Putin that Ukraine historically and rightfully belongs to Russia, and the dictator’s far-reaching goal of destabilizing NATO. Snyder is the author of the Second World War history “Bloodlands,” as well as “The Road to Unfreedom” and “On Tyranny”—which warn of the dangers that imperil American democracy. Running an oligarchy in which corruption is universal, Putin “is basically stuck with spectacle, distractions—the old bread and circuses idea,” Snyder says, “but also is working from a situation where you want to bring other countries down to your level. . . . With that, you can understand their intervention in our elections, or the way they talk about us: they want to bring out the elements of us, both rhetorically and in reality, that are most like the way they run the country.” Putin’s governance of Russia and his foreign policy, in other words, are intricately entangled. “I tend to think [the threat of invasion] is about the Biden Administration, in a pretty fundamental way,” Snyder believes. “If your goal is to undermine NATO—let’s accept that that is their sincere goal—who do you want to be President? Trump.” The crisis, he says, “puts Biden in a very bad position. It’s very hard for Biden to look strong. . . . Insofar as there is a strategy here, it’s about dividing NATO members and putting pressure on the Biden Administration.”
