Earlier quoted context omitted.
So what else is the goal? How many dead Ukrainians to achieve which goal in which way? Please be specific edit: I get that this sound snarky, but it will hopefully drive home the point. Unless you have a 3rd alternative to agreeing what ever the man with the nukes understands under "demilitarization and denazification" and joining a death cult with mandatory membership i dont really get what i can tell you.
> How many dead Ukrainians to achieve which goal in which way? Russians, not Ukrainians. Ukrainians will defend their country and the Russians won't have the stomach for a prolonged insurgency, just like in Afghanistan. Afghanistan led to the fall of the USSR, and Ukraine will now lead to the fall and breakup of Russia.
What ever solution you propose will have a cost in Ukrainian lives and that cost is largely determined with what Russia is willing to do. With their ruthlessness reducing their casualties massively.
