I'm no international relations hawk though, so I'm keen to hear opposing viewpoints.
Our (the west's) response to warmongering has been to trickle just enough resources and monies to keep Ukraine from losing but not so much that they win. The "donated" resources of course need to be replenished, the military industrial complex is quite literally making a killing.
At this point the question of declaring a firm stand against warmongering is lost. It's three years and going, warmongering as it turns out is fine. I hate that. My tax dollars are going towards endlessly and needlessly extending human suffering for the benefit of the military industrial complex. I hate that.
So I say, enough of this bullshit. Unless we suddenly send in so much support that Ukraine decisively wins very quickly, I don't want to see a single cent more of my tax dollars going towards this. My taxes are not blood money and the military industrial complex can go fuck themselves.
The only thing is, what happens next if the West pulls out? Ukraine's military collapses, Russia moves in on Kyiv, Putin gains another Belarus-like satellite state, and at least considers encroaching on Estonia, Finland etc... . It's more than just the principle of whether warmongering is acceptable - a lot of people will suffer as a consequence and possibly for decades to come. We have to be really careful to consider which is worse in the long-term.
I think the West was making the best calculus it could as the situation developed. Sure, you can say we should have known Putin was bluffing about redlines. But the downside of all out war is high enough that, when multiplied by the probability, you still get a bad number. I think it's reasonable that Western governments played it cautiously and hoped for a different resolution (like a successful internal coup).
But yes, now we are where we are and it sucks for Ukraine.
For what it's worth, I've been critical of our (American, subsequently western) response since the first one. Speaking as an American, our response was and still are lukewarm and thus ineffectual in declaring a firm stand against warmongering. I was heartbroken and then angry at being told how (not) valuable world peace actually was.
What Putin did was declare war against the very notion of peace, and the west fucking surrendered it in the worst way possible after preaching so passionately about peace to everyone everywhere everytime.
