I have no clue what to do about Ukraine vs Russia. But Russia’s invasion of Ukraine is unacceptable.
I do know what to do about Ukraine. Go back in time a dozen years and then decide to leave Ukraine as neutral, not invite them into NATO or try to train their military, and not provoke Russia while I built up my maritime forces to keep my own borders secure and deal with China. In other words, not get into the mess that those blind to the meaning of a map got us into.
Ukraine? What about the autonomous republics of Donetsk and Luhansk?
What if someone stole your car, and you saw it sitting in a garage somewhere across the state line ? What would you do ?
