hours. some reports suggest that putin has had setbacks. do you think he is to change tactics are what are we going to see? >> i think you're going to see a continuation going along with what david said. you're going to see a lot of encirclement of these major cities. what that's going to do is it's going to isolate their troops. troops are going to be brought in. ukrainian troops are going to be defending the cities. if russia comes in and encircles them, it contains those trips trying to protect those cities which leaves the rest of the country free to be taken over. ukraine's only option to them i think is going to be guerrilla warfare. they'll have some success with that but again, they're going to start down in the south. as we see what they are doing, as david said, they are moving slow up top. were going to see a lot of encirclement and the major cities i think coming up.
