Supporting Ukraine militarily and making sure it wins is a moral imperative, says Kasparov.A staunch critic of authoritarianism, Kasparov wrote about the dangers posed by Putin's rule for years.His 2015 book, "Winter Is Coming: Why Vladimir Putin and the Enemies of the Free World Must Be Stopped," outlined Russia's political threat to global security.Over the past three years, Kasparov has repeatedly argued that any chance at Russia becoming a democratic country not only requires its total military defeat but a shedding of its imperialistic legacy — a stance not widely embraced by other Russian opposition figures.In an interview with the Kyiv Independent, Kasparov shared his thoughts on the current state of the Russian opposition, why they're looking for a "good tsar" to replace Putin, and why he'll push back at those who insist it's "Putin's war" rather than Russia's war.This interview has been edited for length and clarity.The Kyiv Independent: Living in the West, you're well-placed to comment on its perceptions of Russia.
