Yes, by giving Ukraine to Russia.
We know how it works if you try to appease fascists, come on.
It's also the responsible thing to do to look at the prospects of forcing a war though, when the Urkainians are so heavily outgunned. 200,000 Ukrainians have died in this fight. Maybe 50,000 Russians have died (its hard to find out specifics). The US wants to fight this war on the cheap with the Ukrainians taking all the casualties so that Americans won't have to. That is pretty deplorable to me.
Russians have lost a lot too. But the only thing we know is that they are depressingly high.
What about the Eastern European countries' interests whose combined economies eclipses Russia?
Again, we know that playbook, it has played out before in Europe. Today it's Ukraine, tomorrow it's Poland, and your arguments will still be exactly the same: Russia has vital interests in Poland, Russia has occupied Poland before, Poland is outgunned, and why would we care about Poland, really?
And then it's Germany, at which point, again, nothing has changed. Britain and France might use their nuclear deterrence when it's their turn, but if they listened to you, they'd probably say "do we want to end humanity just because we don't like Russia to rule over us? Surely not, humanity is too important to be destroyed over Russia's vital interest to annex whatever is next to Russia" and roll over.
It would end only when Russia invades the US or China, because neither will allow it if their nuclear weapons are still available by then.
