joining me now is the former ambassador to russia, michael mcfall, who knows a lot about the thinkingre, i'm so grateful for you taking the time. i don't want to over crankiness, but it's important to talk about. putin didn't mention i.s.i.s. k . why did you make of putin's initial response? what was obviously a horrific attack were over 100 lives were lost. >> first, it was a horrific attack, and i want to express my condolences to all family and friends who lost loved ones, terrorism is never justified and this was a horrific terrorist attack, the biggest one in 20 years in russia. second, the thing that was very striking to me about putin's reaction is how long it took. he didn't come out right away, he took some time to figure out the way they wanted to spin it. and then when he did make his statement, just as you just reported, he didn't mention i.s.i.s. k, he didn't talk about that particular organization, which by the way, dave had troubles with for a long time, it would have been easy to explain to the russian people why that kind of terrorist group what have attacked them, bu
