There's so much naivete and ego here. It reminds me of people who are more concerned with being right than winning. Many define winning as one or more of:
- Ukraine has the right to self-determination (a principle applied extremely selectively);
- We can't reward Putin for his unjustified aggression;
- "Appeasement"; and
- We (the West in general and the US in particular) have done nothing wrong so why should we give anything up?
None of this matters. What matters is ending this war. It's the best outcome for pretty much everyone who isn't Lockheed, Boeing or Northrop. Or I guess the hawks in Washington who see the strategic value in Russia being mired in Afghanistan 2.0.
There are only three likely outcomes here:
1. Russia conquers Ukraine and rules it directly or through a puppet regime. This seems... unlikely, at least without massive loss of life;
2. Russia is mired in another decades-long insurgency before collapsing. Despite Lindsey Graham's cavalier comments, Putin dying or his regime getting toppled is going to create a huge power vacuum, lots of instability and is probably not going to be good for anyone; or
3. Through diplomacy.
NATO won't enter this war. Put that out of your head.
From a game theory perspective, you lose absolutely nothing pursuing a diplomatic end to this. If such efforts fail, you're in exactly the same situation you are now. There's no downside.
Putin is bad. This war is wrong. But US foreign policy here has been abysmal and is a significant contributing factor in precipitating this war. I'm amazed at how many people can't (or refuse to) wrap their heads around the simple concept that this isn't victim-blaming or apologism for Russia to point say both sides can be wrong even if one side (Russia) is way more wrong than the other.
