I don’t know, it could be, my experience in military strategy is summarized in having lost many times in the Europa Universalis. What I do understand a little more about is politics and international relations and I know that if Russia presented itself to negotiate with a deal that said “if you give me Crimea I won’t ask for anything else” Ukraine should accept without hesitation.
I agree, that’s why in my first comment I said that if that were the scenario it would be a good scenario for Ukraine. The title of this news is what it suggests, how realistic it is, this is another story
