According to an adviser to the head of the OP, as many russian servicemen will be killed as is needed to liberate the region.

Mykhailo Podoliak, an adviser to the head of the Office of the President of Ukraine, believes that as many russian servicemen will be killed in the Kherson region as will be needed to liberate the entire region from occupation.
Podoliak said this in an interview with Radio NV
“There will be no “Kherson People’s Republic”. It (Kherson region) will be released in full as soon as possible, if necessary, in terms of the number of irreversible casualties from the russian military. That is, as many servicemen of the russian army will be killed as will be needed to forget the phrase “russian occupation” in the Kherson region forever. That will be true”, – Podoliak said.
He called the actions of the occupiers and collaborators in the Kherson region purely “propaganda tinsel”.
Referendum in Kherson: what is known
As reported, the russian occupiers planned in early May to hold a referendum in the occupied Kherson region to declare the so-called “KPR”.
On May 7, Podoliak stressed that any statements by russia about “referendums” and “people’s republics” were absolutely insignificant.
