With Russian forces retreating in eastern and southern Ukraine in the face of a masterful Ukrainian counteroffensive, some commentators in the West have argued that the war the Kremlin launched in February must not end with the “humiliation” of President Vladimir Putin or Russia.

In fact, the opposite is true: Putin’s appalling aggression must leave Russia thoroughly chastened on the world stage.

Leaving aside the immorality of this one-sided appeal to give Putin a face-saving exit (no one seems to be appealing for Ukraine not to be humiliated by an eventual peace settlement), can the argument be justified by history or the cold logic of dealing with a nuclear superpower (even one that has been demonstrated to be superpowerful only in this dimension)?
