welcome back. now to a very important interview. our chief international anchor christiane amanpour is with me. you are about to speak with the secretary general of nato, i didn't think of anyone more important to speak of so take it away. >> he is the man of the moment given the controversy and conflicting reporting that is coming out of the back rooms at the nato summit so let me just turn now to secretary general jens stoltenberg. thank you so much for joining me there brussels, welcome to the progr program. >> thank you so much by having me. >> all the allies were concerned and nervous hoping this summit was not going to devolve into a debacle like the g7 summit did with disunity and pulling out of communiques. how would you say you assessed the unity and the success of this summit?
