Nope. As repeatedly stated, it's a war over the use of nukes at all. Ukraine becomes immaterial.
See above. It is vital that the nuclear stalemate be maintained.
Secondarily, the extreme wealth of the West, and the world at large, is reliant on the concept of sovereignty. Going back to the bad-old-days of empire building will make us much, much poorer as a nation if we have to recalibrate our trading economy around countries that can be conquered at the whims of tyrants.
Sure, NATO protects Western Europe, but you don't want NATO to exist, so by your logic every country without a superior military can be taken over by Russia or China, and we are to allow it unless there is a direct interest. And since you clearly will avoid a nuclear exchange at all costs, no direct interest is going to override that fear. There are a lot of Asian countries we do business with. But if China wants to take them, cool. What's the problem?
And you think the world, and especially the US, will be better for this? That sounds like an Ayn Rand fantasy.
It seems like the libertarian/isolationist wing of the right has joined the left in pretending that the things we did to create the present-day world didn't actually contribute to creating the most prosperous period in human history. It just happened *despite* our power projection. It's nonsense. The South Koreans sure are better off. Taiwan is better off. Kuwait is better off. Israel is better off. And all the countries that weren't invaded as a direct result of the United States military umbrella are better off. And we are better off.
Most of your post is a reply to things no one said or scenarios that don't apply.
A whole lot less than historically. Why is that?
I explicitly stated we shouldn't respond with a nuke. We don't need to. Here we agree, and giving a nuke to Ukraine would not lower the tensions. A nuke or two aren't much of a deterrent anyways.
We didn't lob nukes in Vietnam. Also, why was it different? Is this some sort of relativism nonsense? If you can't see the difference between how the West interacted with the world and how the communist regimes interacted with the world, to include the very disparate body counts, you've gone down a path that has no underlying logic. You either believe there is right and wrong in the world or you don't, which doesn't mean you always start a fight when something wrong happens or always do the most righteous thing, but when you start making comparisons as though there is parity between communist China and the United States, then the underlying assumptions have rendered the rest of this conversation pointless.
They did not use nukes, so how does that compare? Ironically, Putin is in fact threatening the use of nukes, but you don't consider that a hollow bluff. Why?
So again, is this the only line? That leaves every country on the planet available for conquest, and given the sad state of Europe's military, Asia, Africa, South America, and the Middle East aren't the only countries that would be at great risk under this philosophy. Essentially, India, Pakistan, North Korea, China, and Russia are free to invade as they see fit. And we will be better off staying out?
I think maybe one of the primary disconnects here is that the isolationists (and I don't mean that as a pejorative) seem to think Ukraine is an isolated incident. I certainly don't. I see Ukraine as the logical outcome of a Western coalition that has lost faith in itself and allowed its strength to atrophy. I think Ukraine is just the first symptom of a much deeper disease. Fortunately it turns out Russia's military sucks balls, but no one in the West or East thought they were that bad off. I don't suspect China, just based off their numbers alone, would be facing the same type of stalemate if they had invaded Ukraine or a similarly sized country.
The USSR was not a fluke. And while the West has evolved into a triumph of human cooperation and restraint, unanimously agreeing to abandon the goal of empire building, not everybody has signed on to that arrangement.
If you believe that China and Russia would be content with merely establishing trading agreements with the countries in their sphere of influence, you have to ask yourself why they haven't just joined the West, since that's exactly what we do in the West. I submit that it's because they have far greater ambitions, namely, rebuilding ancient empires by force.
And they both have nukes, so what exactly are we going to do to stop them?
