One year ago, Ukrainians drove their president out of power -- and out of the country.

It looked at the time like a triumph of people power. But with Russia's annexation of Crimea and intervention in the Donbas, it quickly turned into Ukraine's greatest existential crisis since independence.

To say that the dramatic fall of Viktor Yanukovych changed Ukraine would be a gross understatement. Even under the shadow of war, the country's leadership has become even more determined to integrate with the West and its civil society has become stronger, more robust, and bolder.

But the past year has changed Russia as well. It has become more authoritarian, more expansionist, and more aggressive.

One year ago, Ukraine's president abandoned his office and fled to Russia. And neither Ukraine nor Russia will ever be the same.

On the latest Power Vertical Podcast, my guests and I discuss how the past year has transformed both countries -- and what this portends.

Joining me are Kirill Kobrin, editor of the Moscow-based history and sociology magazine Neprikosnovenny Zapas; Sean Guillory of the University of Pittsburgh's Center for Russian and Eastern European Studies and author of Sean's Russia Blog; and Christopher Miller, a senior correspondent for Mashable.

Enjoy...
