A few questions . 1. Is Russia invading Ukraine? If the answer is no , don't worry about the other questions. 2. If it is , is the invasion justified? 3. If it is justified , what is the basis of that justification?
4. if Russia is invading , what should the Ukraine do? 5. if your answer is negotiate , what should be the basis of any negotiation ,including any territorial outcome.
6. Does Ukraine have a right to exist in its internationally recognized borders? If the answer to that question is yes , are they allowed , in your view , to take action necessary to maintain that existence ? If no , what should they be allowed?
I might add , whatever the actions of other countries prior to the hostilities, these questions have answers that are largely independent of the actions of those countries. cheers
