Everyone seems so intent on shouting that this was a political victory for the UK/Russia, but the real story is the subtext here.
We asked the US to sail with us on our bear poking trip, they refused and changed course. At a time when Russia and China are becoming ever closer this is quite disastrous and will certainly serve to embolden Russia/China. If this had happened under the Trump administration then the USN wouldn't have just followed the RN they would have been told to lead the charge for the best photo opportunity.
This debacle has essentially served as a massive green light to Russia/China that it's time to start pulling Crimea style crap again
