Any stopping point for a war is a wise stopping point. The Russians in this war are just going to keep upping the price of peace. From Caitlin Johnstone at caitlinjohnstone.com:
At the risk of upsetting the entire internet, the annexation of those four Ukrainian territories seems like a great time to end this war to me. Does anyone honestly believe a significant percentage of the people who live there want a massive counteroffensive on their doorstep? I don’t.
The west knowingly provoked this war, the thing experts warned for years would happen did happen, and now Ukraine lost some territory. Rather than risking millions or billions of lives escalating this conflict, it seems sensible to draw a line under it. You can yell “Putin bad!” and “International law!” all you want, but it’s just a cold hard fact that after the annexation the US/NATO/Ukraine tandem is going to be presented with the choice of either ending the bloodshed or massively, massively escalating it. Pretty easy choice, in my opinion.
