Dara Massicot, Russia Defense Expert, Carnegie Endowment for International Peace. European partners are trying to get on the same page about how far they'll go to help Ukraine and make up for the dire US shortfall. German Chancellor Olaf Scholz will host French President Macron in Berlin on Friday to hammer out their differences. Meanwhile, the Kremlin is vastly out producing the west in ammunition and weapons production. Christiane speaks to defense expert Dara Massicot who says it's a bad sign for Ukraine that Moscow is confident enough to accelerate its attacks ahead of the Russian election this weekend. And we take a look back at Christiane's report for 60 Minutes from 1997, looking at the dire state of Russia's army back then. Rod Nordland, Author, "Waiting for the Monsoon". For years, Rod Nordland travelled the world, reporting from conflict zones and risking his life to tell the human stories from Sarajevo, Afghanistan, Cambodia, and more. But nearly five years ago in India, all that changed when he collapsed while out for a run. In the aftermath in New York, he was diagnosed with glioblastoma, the most severe brain tumor with a terminal diagnosis. But Nordland has outlived the 15 months he was told he had, and he's just published his memoir called "Waiting for the Monsoon." He spoke to Christiane about how in facing death, he found a new, and better life. WALTER ISAACSON INTERVIEW: Bill Kristol, Editor-at-Large, the Bulwark.
