send troops, no boots on the ground, but zelensky wants to hear we've got your back, and we're going to the madden, we will help you as much as we can. there's another side to this, john, which is that biden really also has to encourage zelensky to begin to work toward or to put the minsk agreements which potentially could solve that conflict in eastern ukraine that he has to begin to work on those, two. so it's -- there's a balance here. >> and part of the issue from my perspective, anyway, and tell from your experience judging putin, is you're right the president of the united states made clear yesterday this is not a question of american troops. it's not a question of nato troops. they're trying to use diplomacy here, you hold off on the energy sanctions against russia because of the impact it might have on the global prices. if you won't punch vladimir putin in the mouth or the wallet, what is the incentive on putin's side to back off.
