Ukranians hold snake island so they would just as easy sink the russian navy i believe especially with more and more modern kit being delivered . Uk suppplied big guns can hit targets 25 miles away but russian ones only any good up to 18 milesIf they manage to navigate their way through the minefield with some pretty big ships will they not be showing the Russian navy the way through? I know Putin has made a pinky promise not to attack but he might be tempted.
