what we can now speak to christina rosina. she's a policy analyst on u. s. e u relations, nato, and trans atlantic security corporation. she was us from brussels, where she was attending the nato summit. madam, thank you so much for joining us. it's a pleasure to have you on the program. so what have you made, i guess of the latest news conference that we heard from joe by then about 2 hours ago and just what you saw today in general. thank you so much. when we look at president biden's press conference, i think it's a wonderful cumulation and almost cherry on top of a very productive nato summit. i. the big point today was to show america's ongoing commitment to nato just such a contrast to president trump's prior summit. i was on site at nato h q today, and the feeling was one of productive energy. 3 years ago there was a data summit in 2018. i was also president, and there, there was an anxiety in the air. what happened when president tread says something that cast doubt on article 5 or the strength of the alliance today was an entirely different ball gam
