But this is a northeastern part of Ukraine which Russia is trying to turn into another part of the front line as it tries to sort of bring its tide of occupation forward. Now it’s not a given that if Russia does try and mount a spring offensive that it could in any way be successful. It is mobilizing a lot of men but Ukraine has also addressed some of its own manpower issues.
