Your solution extends the human suffering indefinitely. Not only the fighting - but because citizens of Russia are less free than others countries.
When he comes for your family and home are you handing them over without any fuss?
Bizarre.
That phrase assumes that we have the power to stop him without creating a greater loss of life than the death he would create in the areas he wants to subjugate.
It also assumes that if we do enter into a worldwide conflict to remove him and we succeed, that whatever and whoever is left will be less tyrannical, less expansionist and less likely to create suffering.
And to answer your question…if he comes for my family and home, I will fight for them fiercely, because I will likely have not yet been nuked off the bloody planet by some “well intentioned” warmongering jackass from halfway across the globe who thinks he is doing the world a favor by killing it.
For all of human history borders shift, leaders shift, some are tyrants, some are not…however 2022 by engaging in an apocalyptic war over Putin and Ukraine will not resolve the human nature and eliminate suffering.
But why not compromise instead? It’d be less violence for your family.
The problem is the level of sacrifice required in a worldwide conflict that may include nuclear to “take Putin out” only solves the problem of a single man. It doesn’t create a lasting solution because it doesn’t correct human nature. It doesn’t prevent the next worse tyrant. In fact it makes tyranny much more likely because the possibility of many tyrants that will come from the one.
There just isn't a lot of incentive for an autocratic ruler to destabilize his regime and crash his country's economy to grab a piece of territory at a massive price that the world will never recognize. Putin wanted to annex six eastern provinces of ukraine and create a client state in central Ukraine; not be in a position where he needs to threaten to lob nuclear weapons. Putin was able to grab Crimea precisely because there was no military resistance not because he was able to create a fait accompli that he was able to blackmail the world into accepting. Yet the sanctions imposed after Crimea was annexed dramatically weakened the civilian economy and putin's military buildup.
To be clear, I don't think Ukraine should negotiate or be forced to negotiate but that isn't because I believe Putin would not be deterred in the future.
