How does the Russo-Ukrainian War end?

«The war ends when Ukrainian military victories alter Russian political realities, a process which I believe has begun.» This war is too complex and too dynamic to assume that anyone can predict how it will end. However, as Timothy Snyder lays out, it’s important that we imagine it. «Our imaginations are trapped by a single and rather unlikely variant of how the war ends: with a nuclear detonation. I think we are drawn to this scenario, in part, because we seem to lack other variants.» (For more context, I highly recommend Snyder’s book «On Tyranny: Updated with Twenty New Lessons from Russia’s War on Ukraine»)
