Crimea, specifically the Kinburn Spit, is the tail end of a Prince Rupert's Drop, snipping it will begin a broad dismantling of the russian frontlines.

These droplets are characterized internally by very high residual stresses, which give rise to counter-intuitive properties such as the ability to withstand a blow from a hammer or a bullet on the bulbous end without breaking, while exhibiting explosive disintegration if the tail end is even slightly damaged. In nature, similar structures are produced under certain conditions in volcanic lava and are known as Pele's tears.

Preston Stewart's recent interview with Rob Lee explains it well.

Ukraine has chased russia out of the sea, that is why Ukraine can decisively take Crimea.

Thanks, but that's not really a clear answer. How would even a fully evacuated crimea lead to "a broad dismantling of the russian frontlines"?

One of the most fundamental aspects of warfare is dismantling the enemy frontline by creating/finding a break in them and "folding" the break back to encircle enemy forces.

Try reading some military history!

Right, but crimea isn't a frontline, which is what i was saying

Crimea isn't a frontline in the same way fish stuck in a barrel looking up past the surface at a machine gun don't consider the edges of their barrel a frontline.
