for them? and a second question. you said time and time again the pretext that russia gives is false. i'm curious if if he looks you in the eye and tells you lies to your fece and why humor him with written response next week if that's the case? >> thanks. first, again, we're not waiting to take action to counter r russia. as i said a moment ago, we've committed more security assistance to ukraine in the past year. i think something like $650 million than at any previous time going back to 2014, when russia invaded ukraine. we're continuing to provide that assistance. we have additional deliveries that are scheduled in the coming weeks. as noted as well, we've been engaged in stextensive diplomac around the world, rallying allies and partners together in the face of russian against against ukraine.
