Russia is firing warning shots off the Isle of Wight: How worried should Britain be?

While warning shots are not unheard of, they are a last resort when a vessel is behaving in a threatening way...It seems, since this is irregular behaviour, like the Russians are trying to indicate that the vessels they dispatch can do more than protect their own shipping and will also be a disruptive presence in and around the UK. This would seem to be a way of disincentivising further interdictions.”
