Pretty self explanitory don't you think? Simple straight forward logic not your strong point?
And to correct your falacy, it wouldn't be "reoccupying" it would be Ukraine getting their land back. Facts matter.
The invasion is already a for nothing failure since Putin failed to conquer all of Ukraine like he wanted.
If you're pro-war, pro-Putin and you want to go back to the days of allowing fascist war criminal regimes to invade and forcibly take land from neighbouring couintries then no you wouldn't want Putin to end his war.
