Putin goes on to say
”Our proposal is not to freeze the conflict, like how the west wants it, but to end it. I repeat, this is not to freeze the conflict, but for its final completion.”
iirc DPR and LPR are already part of Russia, they would need to do new paperwork on Kherson and Zapo though
EDIT: I did not recall correctly
iirc The DPR and LPR joined Russia the same day as Kherson and Zaporozhye.
