The Czech Republic is now leading an international effort to deliver a million and a half artillery shells to Ukraine within a year. Czech President Petr Pavel - a former army general, and senior NATO official – joins Christiane from Prague. The world's biggest democratic exercise is underway in India as nearly a billion eligible voters decide whether Prime Minister Narendra Modi deserves a third term. CNN’s Will Ripley explains what’s at stake for this crucial US ally.

From the Amanpour Archive this week, we revisit Christiane’s conversations with the stakeholders at the center of the aborted 2015 nuclear deal, which would have reshaped the Middle East as we know it. And, with military aid locked up in congress, Ukraine’s air defense crisis deepens by the day and Putin is pressing the advantage. Christiane asks Donald Trump's former Defense Secretary Mark Esper if he thinks GOP holdouts have fallen victim to Putin’s propaganda.
