Whatever happens next, it seems like the international order got what it wanted, which was to mire Russia in a bloody and costly war. Now they are just trying to prolong the costs by backing Ukraine and sending their people to die. Probably foreign fighters from all over will now flood Ukraine and try to create a Syria type insurgency. Meanwhile, they are sanctioning Russia and while some of these sanctions are only symbolic, I'm sure the ones that are being reserved for last will hit the worst (SWIFT payment disconnect and so on).
The consequences of this are hard to foresee, especially since there may be a complete black out between Russian and U.S. foreign relations, and the total segmentation of the world in half. I don't think we've seen the likes of this since the Cold War. How does it play out? It will be hard to tell but I think we can expect that having the Russia/China bogeyman will be very useful for the global elite, who can basically carry out whatever sinister agenda they have (cyber attack, biological terrorism, limited nuclear deployment, etc.) with impunity by blaming the entire thing on Putin. Economically what will happen is a whole other topic.
In effect, what we're witnessing has a large psychological component to it. The way Russia and Putin are being treated is strikingly similar to the way Covid was initially treated in 2020. The idea of Russia expansionism itself uses similar terminology to when the virus was "spreading" across Europe, and "containment" was necessary. Of course, remember that borders remained wide open initially and the virus was unconstrained long enough to pretend the situation was a dire. Here too, our diplomacy failed (intentionally) for months before it reached this point.
There are many parallels, and many directions this can go, all of which seem to point to further psychological operations and psychological terrorism, restrictions on freedoms of speech and movement, etc.
