sending? are people interpreting that wrong? what do you think? >> no, i think what the president was saying is that we believe that the people of russia will determine their own leaders, that we don't determine mo the leader will be for another country. but the reality is that mr. putin has brought this upon the people of ukraine. he has diminished the ability of his own country and the quality of life for the people within russia. he is personally responsible for all of that. he has lost legitimacy. no question about it. and he needs to be held accountable. >> when you hear the president warn putin not to move a single inch into nato territory, that sounds like a clear red line. but how concerned are you that a mistake rather than a deliberate attack on nato -- on nato land could trying are the u.s. to jump into this war directly? >> well, there is no question we've already seen of course attacks very close to the polish border.
