Why is Germany dragging its feet on sending tanks to Ukraine?

An unseemly split over tanks risks the ironclad unity the NATO alliance has demonstrated in support of Ukraine. Among some allies – led by Britain, Poland, Finland, and the Baltic nations – there is a sense of striking while the iron is hot, before Russia regroups for an expected spring offensive. At the heart of the drama is the German Leopard 2 tank, which is top of Ukraine’s wish list. But the German chancellor is dragging his feet. More than a dozen countries own those tanks, including Poland, which says it will send its Leopards to Ukraine. But it would need Berlin’s sign-off. U.S. National Security Council spokesperson John Kirby joins the show from the White House to discuss what military support Ukraine is getting – and what more the alliance can deliver.  Also on today's show: Marcin Przydacz, Foreign Policy Adviser to Polish president; Delia Ephron, author, Left on Tenth. To learn more about how CNN protects listener privacy, visit cnn.com/privacy
