The Ministry of Dark Humour and Fantasyland tales must have been under budget cuts to come out with the story of "good will gesture" to leave Snake Island. I confess I had a good laugh at that one.
Despite how fancy and cool this island looks from the strategic point of view (perfect for early warning or as naval base) Ukraine decided long ago that is much easier to attack than to defend. The RF Chief Psychos had to first loose the Moskva, then a few other minor ships (along with wasting the lives of their crews for nothing) and ground troops to figure it out.
Good gesture my ass.
