Carl Bildt, former prime minister of Sweden and co-chair of the European Council on Foreign Relations, shares his perspective on European politics from the Adriatic Sea.

What does the biggest prisoner exchange in decades tell us about Putin?

First, the huge prisoner exchange, the biggest that we've seen for decades. I think it's important to note that it exposes the nature of Russia and the West, because on the one side, Putin was desperate to get back convicted killers, murderers, and failed spies. I think that was very important for him in order to perhaps improve their other sacking morale of his security and intelligence services after significant setbacks that they've been suffering over the last few years, and then I think the success of securing the release of journalists, brave journalists, and brave defenders of freedom and democracy in Russia. I think it is a good day, both for the individuals, needless to say, that have been gotten their freedom, and also for the fact that it does expose the very difference of nature between Russia and the West.
