>> david, let's pull out the lens a little bit and talk big picture. of course, we know the entire theme of the president's trip so far has been that america is back and also that democracy can stand strong in the face of autocracy. what is your sense, having watched this day unfold, watching president biden on stage now with nato leaders, of course, the military flip side in some ways of the economic g7, how do you think we are standing up right now, especially in the face of china? you heard keir simmons' interview with putin where he was open about the fact that he might be willing to have a military relationship with china. there are new elements around that particular relationship that potentially have a lot of reason to give nato pause.
