How, though? The reality of the situation is that Russia - sorry, Putin - can't afford to be seen as weak, either military or politically, both at home and abroad.So no, don't give up Ukrainian territory, don't stop supplying them, but at least use the combined power of NATO to get to the table with Putin...
In terms of domestically, his power base is built on a combination of his image and repressive social mechanisms. Many like him; many others are scared of him.
To come to the compromise that Ukraine find palatable would potentially undermine all of the above because the 'mighty' Russian army would have failed.
From there, would you be surprised to see regional conflicts continuing to stir, as Russia's power within its previous sphere of influence would be undermined?
We could talk about it in a lot more detail, but let's look at the Ukrainian perspective. Like I said, Zelenskyy couldn't afford to make compromises that'd suit Russia.
Nor would he want to. Ukraine has not been the aggressor: it's their country being decimated; their population being raped, pillaged and murdered.
To make a compromise now, that suits Russia, would leave Ukrainian soil and people under Russian control, and we've seen how that turns out.
Also, it would possibly embolden Russia to finish the job in the future. There will be discussions taking place; there will be political manoeuvring towards an end.
But right now, I can only see one way in which NATO can use its combined power to bring Putin to the table, and that's continuing to bludgeon his armies.
Eventually, they (and Ukraine) will have to come to the table. The sad part of this is that people will suffer and die in the meantime.
