him who was in kyiv yesterday. his other aides, as he walks down the line. john kirby, obviously amanda sloan we had on yesterday from the national security council. but yeah, sara, to your point, i mean, that has been poland s fear, and moldova s fear, and all of eeastern europe s fear that they could see something similar. it s an imminent threat when they talk about what thkis coul look like, and why they are so invested in what the outcome of this is going to be.
