In the early hours of Tuesday, June 6th a major Dam on the Dnipro river in Russian occupied Ukraine suffered catastrophic damage. Floodwaters are now rushing downstream and sending tens of thousands of people fleeing. The path of these destructive floodwaters roughly follows the frontlines between Russian and Ukrainian forces in Southern Ukraine and this breach comes just as Ukraine's much anticipated counteroffensive gets underway. This obviously raises the question: did Russia sabotage the Kakhovka dam to thwart a Ukrainian counteroffensive?  I'm joined today by the former US Ambassador to Ukraine John Herbst.  He is a retired career foreign service office and now the senior director of the Atlantic Council’s Eurasia Center. We kick off discussing the destruction of the Kakhovka Dam, including the likelihood that it was deliberately destroyed by Russia. We then have an extended conversation about what the destruction of this dam means for Ukraine's counteroffensive.\
