The US and its NATO allies are swiftly warning of retaliation and catastrophic consequences for Russia should President Putin follow through on pledges of nuclear warfare. Many are wondering just how far Putin will push it, as Ukraine continues to bust through Russian lines after weeks of a successful offensive in the east and now the south. The key city of Lyman in Donetsk is now back in the hands of Ukrainian forces. Correspondent Nic Payton Walsh was the first TV journalist to visit the city and he joins the show to discuss.  Also on today's show: US Senate Democrat Jeanne Shaheen, a senior member of both the Foreign Relations and Armed Services committees; former Brazilian Foreign Minister Celso Amorim; Scott Armstrong, author of Adrift: America in 100 Charts.To learn more about how CNN protects listener privacy, visit cnn.com/privacy

The UK has been swept up in a week of economic and political turmoil, with Prime Minister Liz Truss’s Conservative government coming under increasing pressure over its controversial tax cut plan. Financial markets are roiled, the British pound tanked, and the IMF issued a rare rebuke. Meanwhile in Italy, the electoral success of Giorgia Meloni marks a lurch to the far right that will see a party with roots in neo-fascism enter power for the first time since World War II. And in the US, the latest January 6 hearing had to be postponed due to the devastating arrival of Hurricane Ian. Political chaos often acts as inspiration for Armando Iannucci’s work. He’s beloved for his comedies, looking at the absurdity of politics in The Thick of It, Veep, and The Death of Stalin. His latest work, Avenue 5, is a sitcom about a tourist spaceship thrown off course. But as he explains to Christiane, his goal isn’t just to poke fun at those in power, but increasingly to try and shore up our fragile democratic norms. Also on today's show: Pulitzer Prize-winning investigative reporter Jodi Kantor; comedian Hasan Minhaj.To learn more about how CNN protects listener privacy, visit cnn.com/privacy

One of the strongest storms ever to hit the US is causing catastrophic flooding and destruction across hundreds of miles. Speaking this morning, Florida Governor Ron DeSantis said the storm is “basically a 500-year flood event,” and the government confirms that Ian produced “one in a thousand-year rainfall” in some Florida locations. It embodies a trend in recent hurricanes, as warmer water – driven by climate change – fuels stronger, more destructive storms. UC Santa Barbara Professor of Environmental Politics Leah Stokes is a climate policy expert and joins the show to discuss.  Also on today's show: historian Nina Khrushcheva on what's behind Putin's annexation of Ukrainian territory; Katy Hessel, author of The Story of Art Without Men; Brennan Center for Justice Sr. Fellow Ted Johnson.To learn more about how CNN protects listener privacy, visit cnn.com/privacy

It's day 223 of Vladimir Putin’s war on Ukraine and the president is upping the ante. It’s believed he will move this week to annex the areas under Russian occupation, after claiming an overwhelming mandate in sham referendums there. Ukraine, Europe and the US reject the whole process and Kyiv says Putin will try to make residents there fight for the Russian military. Meanwhile inside Russia, people – mostly men – are voting with their feet: they continue to flee the country in droves, desperate to avoid Putin’s forced mobilization, as Melissa Bell reports.  Also on today's show: former US National Security Council Senior Director Fiona Hill; Jennifer Egan, author of The Candy House; AFL-CIO President Liz Shuler.To learn more about how CNN protects listener privacy, visit cnn.com/privacy
