you do have russian officials and ukrainian officials showing up to see if there is a possibility of progress, but russia's stated demands are still nonstarters for ukraine and the west. that includes demilitarization, that is lay down their weapons and also basically a declaration of fealty to russia, which ukraine does not want to do. now, a lot of that is dark, right, as we wake up this morning, and describe it, but on the flip side, you do see tremendous progress of the west, u.s. and nato getting weapons into ukrainian forces. pentagon saying yesterday hundreds, hundreds of stinger missiles just in the last couple of days. that's a tremendous acquisition for ukrainian forces on the ground. germany pledging nearly 3,000 shoulder fired missiles and that's one reason russia does not yet have air supremacy, those are dangerous weapons. so you do still have some leveling of the battlefield, but the advantage remains clearly in russia's camp, john. >> jim sciutto in lviv, thank
