I think its too late for that. Think Ukraine will push for Putin to have consequences, but I don't think they have enough leverage for that just yet.
The situation is incredibly complicated, but I see a few scenarios:
- Russia succeeds in their siege and installs puppet government, however with a lot of casualties. The west and NATO probably convey their disappointment, continue with sanctions and the diplomatic divide. Ukraine will be split. At least with LDR / DNR with Russian interpretation.
- Ukraine succeeds in holding off the pressure, NATO involves themselves more directly (already partially happening). Russia will unleash their anger - this is the worst case which comes with a lot of unpredictability in terms of destruction and casualties.
- Ukraine / Russia come to an agreement of neutrality. This is becoming highly unlikely as Ukraine will seek revenge for what has been happening till now, Russia will have to remove some of the officials and install theirs - this will never happen under current rule. So the above two scenarios are more likely :(
