and american military writers used to talk about the expectation that when the ukrainians really punched through, the russians would collapse. that hasn't happened so far, has it? it hasn't happen, because they haven't been able to punch through. i mean, i think there is a morale problem in the russian lines. there's no question about it. a lot of them, a lot of the russian soldiers, don't want to be there. remember that, you know, this whole thing was supposed to be over in a matter of days. they're not particularly well fed or commanded or led. they're in a relatively good position, the russians, in that where they're dug in in these lines, they've got a lot of overhead cover, they've got artillery protection, they've got helicopters backing up behind that, they've in some cases got air superiority. so then quite a strong position. but you're absolutely right, if the ukrainians were able to find a way through the minefields and drive a wedge through those lines, i think it's perfectly possible we could see mass desertions and fleeing.
