No, see, *you* want it to happen, because you're seemingly blissfully unaware of how wars tend to spiral out of everyone's control. Russia's weaker than everyone estimated - yes - they're a paper-tiger to a certain extent as far as any conceivable "NATO V.S. Russia & Belarus" hypothetical. All true.
Thing is, they're still a nuclear power, they're all buddied-up with China more than ever before, and you'd better believe Russia's more than capable of spreading a whole lot of worldwide fuckery if inclined to. They're weaker than NATO. That also doesn't mean much in the scheme of things. Just because Putin's not insane enough to start setting off tactical nukes on his western frontier against Ukraine, doesn't mean that he (and his entire group of military poobahs and anyone who might seriously succeed him if something mysteriously happens to Putin) isn't just fine with taking everyone down with him if Russia's seriously on the back foot and looking to become western-Europe's bitch. There are levels to this.
"F-16's to Ukraine to help them out, we'll even personally train up your pilots on our dime & time?" Cool. Awesome. "Here, take some of *our* pilots on top of that, and here's the best way to set St Petersburg on fire" is *not* a precedent anyone wants to set. Not even just regarding Russia in a vacuum, but thinking bigger with China and future potential situations with say India or Pakistan etc either.
I get the tough talk, it feels good. Russia's in the wrong, let's personally smack them around a little bit. Puff out your chest, push the bully around some. Thing is, the reality's a whole lot more bleak than that, and while Putin's been bluffing/saber-rattling on the nuclear stuff to a certain extent, there *is* a line where nuclear powers, any nuclear power, are going to be all "fuck it, everyone dies, me, you, everyone". Escalation has its limits with enemies like this, even when morally justified.
