this -- these events might affect the war in ukraine because certainly on their face a weakened vladimir putin would potentially be good for the ukrainians. but i think on the flip side there is this question that is being asked now at the white house, at the pentagon is what president putin might do if he feels cornered, if he feels boxed in? will he lash out? and remember, michael, russia has the largest stockpile of nuclear weapons in the world, and so this is sort of an ongoing worry for the white house. and i do think that has informed some of the strategy that you saw unfold over the last two days, which is basically to say nothing. and, in fact, president biden when he did get on that phone call with leaders from europe this morning, he did make the point and the leaders did agree that trying to say anything more than they've said had the potential to allow president putin this pretext for claiming some sort of american or nato
