officials and their families. joining us now, former u.s. ambassador to ukraine, steven piefr, the welcome perry fellow at stanford university and also with us, cnn global affairs analyst and time magazine contributor, kim dozier. welcome to you both. mr. ambassador, let me start with you. and as we learn more about bucha and the potential that there are other cities like this where we see these atrocities, president zelenskyy says that it s going to be hard to talk about peace when you see what s done. are peace talks really possible now with russia after what we re seeing? well, let me begin by saying the images that you see in bucha are absolutely horrific, but they seem to be part of a pattern. russia s indiscriminate shelling of mariupol, kharkiv, chernihiv without regard to where civilians are and i fear you re going to see more buchas because this kind of atrocity, this kind of brutality seems to be very fairly common practice with the russian military.
