So what happens when the Uka starts to reach the russian border. The general belief is they will not cross it in force, or for any period of time, but how do they defend it. The length of the border will bleed them dry if they try and defend everywhere along its length. If putin does not concede how do they deal with the likelihood of ongoing incursions.
I guess the question is what does Ukraine do next if/once it has expelled russia ?
