In a better world Ukraine would be equally armed, have same size army as Russia. And would tell imperialist scumbag Putin to eff off about his warm water port. I have had dreams about this.
The next best outcome is that Putin croaks next week, and the Russian army slinks back to Moscow and points east. This can happen! Anything can happen.
None of that is going to happen...
You assume that Putin’s successor will be another Gorbachev.
