"Here is actual reality...the Russians after a couple of small attempted assaults left the island completely"
What is your evidence for this claim, and why would Russia willingly abandon a strategically crucial island?
You are either telling fibs, or you are saying Russia was defeated and forced to abandon the island.
Your further claim that "Ukraine then launched a big attack on an empty island" is demonstrably false, as direct footage of moving targets at the island being smoked by Ukrainian drones has already been posted on here.
