Ukraine was preparing an operation to return Crimea?

Ukraine prepared an operation to return Crimea by 2023. This is reported by The Economist.

The publication refers to the words of the ex-commander of the Airborne Forces of Ukraine Mikhail Zabrodsky. He said: “Operation on the return of Crimea is not just possible – it was planned by 2023.”

Zabrodsky claims that “if we published these plans in the media, then we would not have achieved anything.”
