Putin's officials announced that the Putin forces will pull out of the city of Kherson.

Assuming this is serious, Ukraine should not let those soldiers leave without a fight. If they do, Ukraine will have to fight them on another front next year. Ukraine now has the opportunity to try to cut them off so that the survivors are compelled to surrender. The loss of Kherson will embarrass Putin, but the loss of thousands more troops will weaken the Putin forces.
