into ukraine i'm sure there is very robust intelligence sharing with ukrainians, and i couldn't help but think about what a couple squadrons of ra-10s, ground attack aircraft could do with that column, which doesn't reflect very good convoy security practices, just bunching up those vehicles like that. that's a target rich environment. so i'm sure there is more that is being done that is visible and more that could be done obviously. no fly zone, but i don't think that's in the cards now. >> as we look at what is being done, and as you just talked about, this effort to surround, to cut off kyiv, is it more beneficial for vladimir putin to try to splinter ukraine at this point and to wage some division in that way than it is to try to take the country as a whole?
