Good for them — though I still think the operation is strategically pointless from a military perspective. Politically, though, it’s been a rousing success. It shows that Putin is weak, Russia is overextended militarily, and that Ukraine can execute a meaningful op if they are not held back by absurd restrictions on their use of force against a brutal occupying enemy.
And not as important but still funny, it makes the Putinoids like Ian Welsh fucking apoplectic. That is a small reward, but a nice one nonetheless.
