In a shockingly provocative move, the UK's HMS Defender purposely sailed into Crimean territorial waters on its way to Georgia.
Press reports suggest that there was a dispute between the UK defense and foreign ministries over whether to violate Russia's claimed territorial waters with a heavily armed warship. According to reports, Prime Minister Boris Johnson himself jumped in to over-rule the more cautious Foreign Office in favor of confrontation.
As Johnson later claimed, because the UK (and the US) does not recognize Russian sovereignty over Crimea, the UK was actually sailing through Ukrainian waters. It was an in-your-face move toward Russia just weeks after the US and NATO were forced to back down from a major clash with Russia in eastern Ukraine
This time, as was the case in eastern Ukraine, the Russians took a different view of the situation. Russian coast guard vessels ordered the HMS Defender to exit Russian territorial waters – an order they punctuated with rare live fire of cannon and dropping of bombs.
