Just a small serious point for the sake of it.
We are belatedly buying maritime patrol aircraft to protect the submarine fleet. So it needs protecting. I don't buy the stuff about the oceans being transparent or the Russian "underwater drones" having magical powers. But I also don't buy the notion that it is always impossible to detect our submarines given how much bragging we hear about tracking Russian submarines.
Why can't we have a discussion along the lines of "nothing is certain, nothing is for ever, this is the best option for now, on the basis of the information we have".
Is there an English nickname for the manoeuvre known as the "Crazy Ivan"?
