Yeah,said this myself the other day.I don't really see the point.
Ukraine are very unlikely to invade Crimea from the sea.
As well as the fox holes or whatever they call them,they have miles of trenches and Dragons teeth.
Along with at least 9 warships,think its 7 ships in The Black Sea and 2 in Sea of Azov....5 also lurking in the Med...dont see them 5 getting involved though.
Slava Ukraini.
